prescott 3,4ghz benches

[Strawa]

hi, im playing around with prescott 3,4ghz and gigabyte 925x board.
here are some benches
(DDR2 533, X800pro)
super pi and half life 2 at_canals_08 demo

------------spi 2m ---------------at_canals_08.dem

3,2--------------------17x188-----640x480 98.84 fps
3,3---------1m31s---17x194-----640x480 97.58 fps
3,4ghz-----1m28s---17x200-----640x480 96.48 fps
3,5---------1m26s---17x206-----640x480 94.88 fps
3,6---------1m23s---17x212-----640x480 94.01 fps
3,7---------1m21s---17x218-----640x480 92.91 fps
3,8---------1m19s---17x224-----640x480 90.84 fps
3,9---------1m16s---17x230-----640x480 89.89 fps

1,38v core, 1,9v ddr2

Scores are wierd, game performances are decreasing with increasing mhz, and spi scores are better as you can see.

Throttling begins over 3,8 Ghz and 63C (according to Gigabyte temperature software) with vcore over 1,45v. (Ive used ThrottleWatch).
It is interesting to see hl2 score at 3,2GHz - higher than at stock speed.
What's ur opinion?

 

[Zebo]

Like my friend Tstep says PressHOT are a "up to 3.8ghz" processor, sometimes.

My opinion is it's even throttleing at default speeds of 3.4...Want proof if half-life was'nt enough try superpi 32M at 3.3 and 3.4...

Maybe get better cooling?

 

[TStep]

Nice work Strawa. I used to see this a little with the P4C cores when going after the wild and wacky overclock, but nowhere near what the newest P4E's are doing at stock. Absolutely incredible to pay for the more performance and get less.

Perhaps in you underclock to 3.1 you'll break 100fps Your tasty results ought to be presented to Intel's shell game department.

You can try something like This Mod from Overclockers.

The stock heatsink without ducting performs poorly: Keeping that hot CPU running Cool and Quiet

Without a duct, even Brute Force air cooling won't do much good if you're recirculating hot air to the CPU.

 

[LTC8K6]

Well, is it throttling or not? I would think throttling would lose you a lot more than that in a game. SPi wouldn't get faster, either. I doubt it's throttling.

Sounds like the vid card is changing.....

Why the quick jump to the conclusion, folks?

 

[Zebo]

2m is way too short to tell.

wow,what an incredible improvement with a simple mod

Explain that one. How would it give lower score as processor clock increasing?

If anything, score would be less high, but still higher, each processor bump since Vcard is the static element here, even finding itself clocking down as it would clock down the same each time...

I've been seeing more and more posts like his...thottle inside case at home... wait till summer..

LOL

Another thing is his mem is taking a hit during these tests and still he is showing improvment at the lower clock settings...Amazing.

More data is needed though like some long term encodes or 32M... Also, static room temps and same case enviroment (fans speeds, closed etc) would help methodology...same mem clocks and latency would also be most helpful but almost impossible w.o using dividers or having unlocked multi.

 

[TStep]

I assume you ran these BMs close cased. Maybe you could try a down and dirty approach to cooling by performing the same BMs open cased with supplemental cooling (desktop fan??) in an attempt to rule out the possible throttling.

 

[LTC8K6]

I don't know how the game can get slower with Super Pi getting faster.

I think he said it isn't throttling until 3.8Ghz....

I am not clear on that, though. What does throttlewatch say, strawa? Is the chip throttling, or not?

I guess it's possible that his case does not meet Intel's specs for that chip.

If Intel's throttling works that well, with that little perf loss, it's friggin' brilliant.

 

[Strawa]

stock cooler instaled, case is open, two 80mm fans are spininig around this preshot - I know this stock cooler wont do for oc but Im surprised that it's getting higher scores when underclocked .

nero wav test: 631 mb, out: mp3pro, 96kbs. stereo, highest quality
time: 2m 38s - at 3400mhz

nero wav test: 631 mb, out: mp3pro, 96kbs. stereo, highest quality
3m 5s at 4000 mhz -235x17, 1,48v

cpu-z reads ddr2 latency as 4.4.4.12


pcmark04
3,4ghz- cpu score - 5157
4,0ghz- cpu score - 3027

It would be nice to see someone's else scores with same or similar clocked cpu.

edit:
throttlewatch says up to 40% when cpu is over 63'C (according to Gigabyte easy tune software, bios readings are much higer -my guess it is over 80'C)

 

[Zebo]

That's a crying shame.

OK you're kinda stuck with it, right. My suggestion is go over to heatsinkfactory.com and get yourself a thermalright XP120 or XP90 and a good high throw 38mm wide fan with lots of static pressure to keep that bad boy from going into idle mode. Imean you paid for a 3.4 you want to run 3.4 all the time. Also apply the thinest thermal interface possible, just enough to fill in microscopic vallys, and apply HS with major pressure for best contact.

aka "poor mans watercooling"

 

[TStep]

Ouch...If you are intent on keeping the setup and get the additional cooling, you might want to try that nero wav BM and a couple of others at a couple of different frequencies and find the one that performs the best overall and live with it. It would be ashame if your best performance came at a lower frequency than stock.

If it did, I'd try to speak with Intel, explain the situation, and see if you can't get a different cpu out of them. It seems to me like the cpu at stock is acting as though it is highly overclocked from your initial round of benchies.

BTW: how would Intel speed bin these parts if clock throttling just takes over, reducing the effective frequency, and making the cpu stable at whatever speed it will initally boot at? You essentially would have different PR ratings at different temps similar to how quality PSUs are rated.

 

[THUGSROOK]

LMGDFAO!
you guys posting this info are great!
now do you understand why im still on a 2yo system?

sell it and get AMD

(thx for pointing me here Zebo)

 

[Zebo]

Ya you should test 3.2 and 3.3 too... Also 32M is good.

Hell no wonder p4 presshots can OC so "well", if your CPU is off half the time you should hit 4.5 on good air:roll:

 

[THUGSROOK]

i cant stop laughing!

OMG this hurts!

 

[Zebo]

Hehe I've been tempted to get one of these bad boys to do my own testing. Inside a case at home, not open air, cold office like all reviewers do... Only thing that's stopped me is many people would say "consider the source" as I'm AMD user and resale is a bitch on these things.

 

[THUGSROOK]

ok ok im calming down now, eh let me catch my breath.....

opinion?
vid card heat takes it over the top!

 

[THUGSROOK]

!idea!
thats why they made BTX! LOL its upsidedown!

hahahahahaha!

 

[bobsmith1492]

You could get around to consoling him after you finish laughing....

 

[stevty2889]

Yeah, I noticed lower scores at higher clock speeds too, thermal throttling is kicking in at 70c for me. I dropped from 3.8ghz to 3.75ghz and my temp stays under 70c now and throttling isn't kicking in. I only noticed the throttling in benchmarks though, didn't seem to affect game playing much even though it was throttling.

im still laughing


well, if there is a problem, id be blaming the moboard right about now.

 

[LTC8K6]

Intel has a list of chassis specs and approved case designs for these processors. but few people pay any attention to it.

Thermally Advantaged Chassis - no not BTX

i am sorry but that is a bunch of bunk...Intel supposedly comes out with a newer revised core in the prescot and now we have to change the whole system cause Intel can't get there act together and quit producing these power hog, thermal nuclear devices!!!!

Then give us a product that is:

1) worse clock for clock then its predecessor. No need for a revision as far as I have seen, considering the lame amount they have been able to ramp them up. They hobble it with a 30 stage pipeline to be able to ramp it higher and this is the best they can do...Oh trouble!!!

2) warmer per clock: Have to have better case cooling, stock cooling out of the box is ineffective unless you have like 12 case fans so you have to buy aftermarket cooler....BS!!!! I guess Intel should spec water blocks and force us to get water coolers...LOL!!!

3) More power consumption. Unprecedented amounts of power needed...

I fail to see where prescott was an upgrade..Please show me!!!
