cache- 4mb vs 8mb

Is there is a significant advantage to having a processor with an 8mb cache instead of 4mb as applied to a DAW?

I am reading this thread w/ intrest as I am deciding on a new computer.

so what ya'll are saying is that I will have issues running cubase 5 on a win7 system when i try to use my favoirite 32bit plug ins inside 64 bit Cubase 5. The 32 bit plugs will not work inside 64bit cubase 5?

That is should check your old plugins and see if they have a 64bit version and install those if your going to use Win7 64bit and Cubase 5 64bit.
There is a program out there called J-Bridge that is supposed to "bridge" 32bit plugins to the 64bit environment, but you would still need to make sure that works with your specific plugin...

I think I'll just run Cubase5 in 32-bit for now. with 8 gigs in the new computer I should still have 4gig left for Cubase even after windows 7 pro loads...

djmukilteo - you are running the ZED I see - with a 800 FW card. Any issues? I have read that it works well on a 400 card as well... True or not?

Some devices don't play well with the combo 400/800 cards. To be safe, either buy one or the other, or by one of each. Make sure they have TI chips.

If you have a bunch of third party plugins that you can't live without and they don't have newer 64bit versions then 32bit Cubase will work just fine in Win7 64bit. I just finished installing it that way on a friends setup. If your using just the plugins in Cubase 5 then you don't need to worry about those.

Neither Win7 or Cubase will ever use that much RAM when loaded or running...having more RAM will keep your computer from stalling during streaming recorded audio and managing bus related tasks to HDD....the more you have the faster and smoother your computer will seem to run.....Win7 only needs 1Gb to run....Cubase only needs half that!

The only reason I have both the FF800 and ZED 16R is because I had the FF800 first and then wanted a "hands on" analog mixer for ITB/OTB mixing, so I bought the ZED. I could sell the FF800 and just use the ZED, but I like the FF800 too much and can't let it I use both. I have the ZED hooked up as 16 channels ADAT in/out to the FF800 and it works great that way...but I could use either unit. The stability of the FF800 with FW/ADAT is so good IMO and it has never missed a beat. Some people have had issues with the ZED FW drivers so I've bypassed all that by going through the FF800. The ZED alone with its FW would be all anyone would ever need with all its features to run 16 channels..and it has a real distinct analog sound to it, which does sound different than the FF800. I wouldn't say it's better or worse but it is different....

Pretty much everything runs into and out of the cache into the having a larger cache available to it will obviously make it operate quicker and more efficiently. Anything the CPU computes or data it moves between RAM to the cache and then into it's internal registers will increase its throughput...
Significant advantage is a tougher question. This all depends on how the applications are programmed. If the programmer takes advantage of the throughput than it could be significant, but in most cases it's not that important to have that sort of performance. You might not notice any difference.
In the case of cache more is always better, how significant 4mb over 8mb is a lot like trying to determine if one A/D/A converter is better sounding than the other. Maybe you can tell maybe you can't

I basically have to chose between
- an i5 3.2 ghz with a 4mb cache -or-
- an i5 2.66 ghz with an 8mb cache
I'm going to be running either Sonar 8.5 or Cubase 5.
I think I understand a little better now how more cache affects the system. Just don't know if it would be better to have the bigger cache or faster processor.

Go search benchmark tests for each and see which has the better specs...
I think you will find the 2.66 might be better but I'm going on memory..
Having the most RAM that is matched to the system bus and is the fastest available is where you will see significant performance and speed!

Thanks for the reply djmukilteo! I actually ended up going with an i7 which was $100 more than the i5 with the larger cache. It's been over 5 years since my last computer so I figured the i7 might help me make it another 5-6 years. Now I just have to demo Sonar and Cubase to see which one is going to work for me. I've always used Cubase until now but I keep hearing great stuff about Sonar 8.5. I've read that it's the only Windows program right now that fully utilizes the 64 bit OS. Is that correct? Thanks again!

Cool....just make sure you get plenty of RAM and buy the fastest best chips you can afford. Win7 is a huge hog so make sure you get rid of anything that makes the thing all pretty looking and go for setting all of the performance settings in the System folder to "best performance" and leave the cool looking GUI stuff for somebody that cares...I just finished setting up a friends Cubase Studio 4 on his new Win7 64bit OS Dell system and the performance went way up after getting rid of all the crap and serious tweaking....without doing that it was just as slow as his previous system!

I believe the latest Cubase version 5.1.1 is 64 bit for Windows 7.

I'm still using Cubase 4.5.2 with a RME FF800 and a ZED16R ADAT/mixer which works perfectly fine for me with my WinXP Pro 32 bit and I have no complaints with Cubase....I tried Sonar LE and to me it was fine just different look and would be a whole new learning curve that I'm not that willing to get into right now....I like my work flow and am pretty comfortable getting things set and tracking which is my main goal...and I'm more focused right now on mixing ITB/OTB with the ZED.

IMHO getting different software doesn't make better mixes or better can create amazing recordings with either package and the main functionality is really the same....the only thing different will be the plugin sets and maybe specialized features that I don't often use anyway.
FWIW....We're always so quick to jump onto a new bandwagon before we've even exhausted the possibilities of what we already have in our own two hands!!

I'm going to be working with 6 gigs of ram so hopefully that'll be fine for a while (what do you think?). I could've gotten 8 gigs but it was either that or the i7. It can expand up to 16 gigs later on if needed. I do plan on turning the settings down on everything that doesn't affect the audio. My interface is a Tascam FW1884 and unfortunately it doesn't appear that the drivers are out yet for Windows 7. So I got the version that has the XP mode on it as well.
Ideally I would like to stay with Cubase for the very reason you cited. I'm a singer/songwriter who mostly just does audio tracking (not much midi at all). I was on Stienberg's website and must have overlooked that Cubase is now 64 bit. Mainly I was just concerned that if it wasn't 64 bit, I wouldn't be able to utilize more than 4 gigs of ram. I have to admit I'm excited about demoing both of the programs. It's been a long time since I updated (I'm still using sx2). Here's some of the stuff I've recorded with my ancient software.

6G of RAM seems like a minimum amount for Win7 already! LOL....sort of like 4G was for XP, I'm positive 8G would be better, but hey you make do with what ya want...right.
So is the 6G triple channel (3) 2G sticks which fills up all the RAM slots on the MB? If so, when you go to try and increase your RAM you might find out you need to change all of the sticks to something bigger. If you get 8G with say (2) 4G sticks then you would probably have another 4G stick you can add later for 12G, but I don't know what motherboard you're looking at or what the RAM configuration you're looking at so I'm guessing here.
FWIW...the 2.66 i5 with 8G would be plenty fast....but that's just the way the technology goes I'm afraid. It's all a tradeoff. The i7 is quite a bit more expensive for what you get....and Win7 can run any 32bit software you have just fine and just as fast, but as far as the drivers for the Tascam, I'm not sure....I do know that Vista drivers aren't all that much different from what they are for Win7. There are some minor differences between the two OS's.
If price is no object and your going for a brand new DAW anyway, then I would go 64bit all the way, but that would mean a major change of everything your using now.
You could see a big difference in your existing setup just by going with the i5 and 8G and then put the saved $$$ into something else....
Listened to your tunes on myspace and they sound really clean!....nice sound!
I'm wondering if you just need a little faster computer and continue working Cubase!
I sent you a friend request

Thanks for the compliment and friend request! The ram is devided into 4 slots - 2 2gig and 2 1gig and it's the 1333 mhz type. I tried to modify the order but it's already being built and unfortunately I would have to wait until it's shipped and then return it if I wanted to make any changes. So I don't know..I guess I'll try it out and give it a real hard test and see how many plugs I can run smoothly.
I'm a little confused on how much of the ram can actually be used in a 32 bit system. I've read that it's no more than 3 1/2 gigs. As I understood, the advantage to running a 64 bit system is that more ram can be accessed. Is all that correct?

The maximum RAM that can be addressed by software in a 32bit operating system is 3.2ish gb. You can't afford the maximum for a 64 bit system. Now that said, a 64 bit os is still limited by the CPU/memory controller/PCI bus. If you're looking at mobo's that can take an I7 this should be a moot issue. I haven't checked out any i5 mobos so couldn't tell you anything about those. Bear in mind that some mobos even with an i7 max at 8gb ram. Check the specs with your DAW builder. If it isn't a DAW builder then check with the computer builder or mobo manufacturer.

4 slots is good then you can upgrade later if you want to...
I have seen some systems where they had filled all the slots with 6G which makes it more difficult to upgrade.
You should be fine though....
I'm not real sure on the RAM memory mapping in Win7.
In XP if you had 4G, it will use 1G right off the bat for system files and then leave you a full 3G to run application and 4G is the maximum address space in a 32bit system. Win7 is a 64bit OS so it's addresable space is way out there, I think its 24G or something like that so you won't have any limitations there. The way Win7 runs 16bit or 32bit applications is it just reserves a block of RAM space and then executes the application within that reserved block as a shell....but still executes all it's system files in another block in 64bit. Win7 will create two program folders...."Program files X86 folder" which is for legacy 32 bit applications and then the usual "Program folder" for 64bit applications....64bit applications aren't that common yet...I'm betting if you get Sonar8.5 or Cubase5.1 they will be the only programs you will have that are...

It's a P55 chipset. I guess it's a new one that was mainly designed for the i5's. It has 4 dimms, each being able to hold up to 4 gigs, for a max of 16. Now forgive me if this is a stupid question (cause I love asking stupid questions) but that does mean that my DAW -as is right now- could actually make use of up to 16 gigs of ram in a 64 bit OS, right?
Hey djmukilteo, how do you like that convolution reverb on cubase? It's not on my current version.

@djmulkiteo-XP, Vista, and Win7 all come in a 32 bit version and a 64 bit version. It is the bit window which determines how much RAM an OS can address. Hardware limitation is a separate issue of course.

@llatht-I don't know which branded P55 board you have for sure. Most of these have a specified maximum total memory of 16gb which is far less than the tech specs of a 64bit OS iteself. You won't be able to pop in 16gb per slot (16gbx4=64gb) but a total max of 16gb. Again the limiting factor in this case is the motherboard architecture. Again I haven't looked at your particular board so I couldn't say whether there are other limiting factors. Go with the DAW builder specs if in doubt.

Matched pairs of ram is still the best way to go and in fact the only way to achieve complete benefits of dual channel DDR.

Ya...64bit addressing would go out to terabytes I the memory controller and number of slots and the RAM chips themselves all need to be part of whatever motherboard you use and they dictate the maximum allowable amount of RAM. Most of the new Mobo's are at 24G of RAM using DDR3 chips up to 1800Mhz clocking speeds.
llatht: What brand of computer motherboard and RAM chips are you getting?
I think what llatht is wondering (and I'm not sure) is if he uses his old Cubase in 32bit mode will the extra RAM do anything for him....and I think the answer to that is Cubase is programmed to use some amount of RAM while it's executing, that might be 1G of RAM space total or it might balloon to 2G at some stage but it I doubt it......Cubase usually states that you need a minimum amount of RAM (1G) to run Cubase so that will be all it will ever need. Now the 64bit version of Cubase might be able to use more RAM if Cubase wrote the program that way to take advantage of the additional memory and speed.....but that's not something I might be able to get that info from the Cubase forums.
