Ye who are wise in the ways of science:
I took the advise of the wise and un-overclocked my cpu for now. Running the P41.6a at 100fsb. Opus's recommended reading put a scare in me.
But, I am wondering what the deal is. I have ran several Arithmetic Benchmark tests and they are all in the same ball park:
Dhrystone- 4200
Whetstone 900/2100
The following were comparison #'s:
P41.6 256L2- Dhrystone- 4269
Whetstone - 898/2096
Celeron 1.5 128L2- Dhrysone- 4536
Whetstone 954/2227
Athlon XP 1600 (1.4Ghz)-Dhrystone- 5269
Whetstone 2141
What is the flippin deal? :confused:
Even when I o/c's to 1.92 (120 FSB), the numbers were only D-5017 and W- 1084/2543
Mobo diagnostic reads temp of about 34/35 during test. ( I know this can be wrong )
At the moment, I am running:
BG7 mobo, 256MB Samsung PC2700, 430w Antec True, Win2K; but using both onboard graphics and and onboard sound. (Santa's bringing video and sound cards.) (don't tell me he isn't real)
Any chance this is part of the problem (I don't see how, but I'm stabbing in the dark here). I know it is killing my memory usage, but c'mon!
And (as if I need to ask more questions) what should my target temp be. I'm going with upgraded cooling as recommended.
Thanks.

Well, in all actuality those temps are absolutely normal. In fact they're not too bad really. When you put a heavy strain load on the CPU it calculates more and produces more heat that way. The hottest it should go is probably 40c which you are seeing. That's why I went with the water cooling system just to keep it lower. Sandra reports 32c for me now with a heavy load on it! My CPU temp readout is busted and I have a new one on the way to me so I'll be able to better gauge it. I tell ya something is wrong with my system as it is because Sandra won't due a burn in properly at the present moment. I have to figure out what is causing it. I think it might be due to the heat sink not properly touching the CPU or something. I need to reseat it but I'm going to wait until I get the new thermister for the CPU temp readout gadget.
As far as your performance...you are running a 400Mhz CPU with a higher count DDR that isn't synchronous...if you had a 533Mhz CPU you would see the difference

Am I understanding this right:
Because I paid more for my memory, my performance is weakened?
The PC2700 was strongly recommended to my because it A) would be useable in the future B) would be good if/when I overclock the cpu C) would NOT hinder performance with the 400FSB.
If I run at 133FSB, that puts me at 533Mhz FSB, right? But...I don't want to go that high at this juncture.
I also just read some P4 1.6a reviews, and it seems my numbers are better than the ones they posted. But according to the Sisandra, a Celeron 1.7 and a P4 1.6 256KL2 are whoopin me? Can that be?

Ok, lets get some info here...
I dont remember what your motherboard is so I'll need to know that...
also does Sandra report that you have a 256 or 512 level cache? If 256 you have a Williamette and not a Northwood P4.
The chipset is going to be a key factor here too if it truly supports DDR 333 or not. The 845G does while chipsets older than that do not. At least "officially"
Are there any warnings within Sandra when you do a CPU or Mainboard report? What happens if you do a burn in on the CPU under high stress at about 10 times. Does it stop or lock up on you? You may not be running everything the way it should be run. Yes you can set the FSB to 133 and see some difference but it's still upping the RAM speed at the same time making it non synchronous still!

Abit BG7; 845G chipset.
Its definitely the Northwood. (Yes,Sandra reports 512 level cache.)
>>>>Are there any warnings within Sandra when you do a CPU or Mainboard report?
--Only things I know about, like 'use a AGP, not onboard..." Nothing major otherwise.
>>>>What happens if you do a burn in on the CPU under high stress at about 10 times.
I ran a 10x burn in while overclocked at 133FSB and that 10% power boost. It ran flawlessly. Temps were acceptable from what I remember.
So there's that.

THANK YOU. :D

You're post said that the 845G supports ddr333. But the (not that I'm saying you are wrong. :) ) site I grabbed that info from says up to 266.
Just asking based on that info.
Thanks.
Well, "unofficially" the 845G supports DDR333...it does support
Well, "unofficially" the 845G supports DDR333...it does support it though as that was the whole point of the G part of that chipset..Graphics and higher DDR support. That was the beginning days of DDR 333 support...the 845PE "officially" supports it!
I know it's confusing and all..the 100Mhz FSB coupled with DDR 333 isn't going to get you anywhere though
Peace

Doesn't this kinda make you go "HMMMMM?"
REPENT, GARY, REPENT! Each night, before I sleep, I'll pray that you return from "The Dark Side". Poor, misguided soul!
I just hooked-up my puter to a Mike-Ometer, and it wouldn't even display the numbers! It just says, "This thing fucking kicks major ass all over that P4 you were going to pay triple for!"
Sorry to be OT, but I just couldn't resist...

...........and I'm still scratchin my head.....
Glad to provide you with ammo, oh smawgy one.
I still don't know what the answer is...
Isn't PC2700 reverse compatible to run where PC2100 would run? Am I smoking the weed?
I'm not grasping the concept apparently with the CPU/RAM relationship. And after I looked around, it seems that the numbers I posted are better than what I saw elsewhere.
Again, though, this could be all the 'things' I ingested in college.
Hey, I a sober dude, and I know I've got enough brain cells to get this. And yet.........
Help me, Obie Won, you're my only hope :D

Oh SOS....have you no shame! lmao!
Shall I post my results from Sandra?!!! If I did I think you would be eating those words!! ha ha ha ha ha ha ha!

As I said earlier...most likely the reason being is that you have a 100Mhz FSB processor and trying to run it with a 133 based RAM...DDR333 is that...DDR 266 is 100...
So, when you change the frequency of the processor you are also changing the frequency of the memory. Depending on the motherboard BIOS you may be able to set each on independently...
I'll post my scores soon...right now my machine is rendering an AVI file for DVD burning....can't do a Sandra test at the same time...just you wait SOS...you'll be munching on toe jam in no time at all!!!!! :D
Are memory ratios different on Pentiums? To my knowledge, and
Are memory ratios different on Pentiums?
To my knowledge, and someone please correct me if I'm wrong, the rating of your DDR SDRAM is double the fsb. Therefore, 133 fsb would yield 266 {PC2100}, 166 fsb yields 333 {PC2700}.
I'm running sync'd at 166. My XP1600+ is locked at the 10.5 multiplier, and I'm using PC2700. My system says that my memory is running at DDR 332, and my CPU is at 1743 {343 over}. It's just as solid as it was at 1400, and not much hotter.
OPUS SAID:
Depending on the motherboard BIOS you may be able to set each on independently.
Yeah, most BIOS' will let you do that, but that will often lead to instability problems. Your best overclock will happen when you're sync'd, you have very good quality memory, you have a good stepping processor, and you have good system cooling.
Indeed, OPUS, post those figures. Hehehe, and I'll go ahead and download the Sandra program and let you know how my <$60 CPU performs!
What I'd really like to see is a P4 1.6G, overclocked as far as it can go and still be stable, and see those Sandra results. I'd be very interested to see if a P4 of a slightly higher rating {that costs twice as much} can keep up with my puter. I'd call this "comparing apples and apples", but these are just shitty little peecees ... ROTFLMFAO
PS ... I still prefer my G4-400.
Alright. Now I'm irked. I decided to really hammer the cpu.

I loaded at giant pic into photoshop (I know...get that thing off my DAW. I will soon enough...)
I used a very large high dpi pic and set it up to liquify/morph the whole thing. A challenging thing. My CPU temp reading (CPU was running 100% for about 3 min to render the pic) jumped from 32.5 at idle to 34 to 35 to 37 to 38 to 39. It just went back to 34 - the calculation ended 3 min ago.
Is that normal? Is that acceptable?
I'm thinking no.
