E8500 Retail Q740A493T better of 2 cpus

[ZoLKoRn]

Nice your chip eva, look very good for see 4G+ by default Vcore but my chip Xeon E3110(E8400 spec) it s_ck it can't boot over 3.7G by default Vcore seem it like high Vcore.

Thanks for answer

[eva2000]

thanks guys

I was just looking through intel's spec sheets and it looks like abs max is 1.45v with max at 1.3625. since most people stuck to the max for conroes of 1.5v, would you or anyone else care to test how well these penryns scale from stock vcore up to 1.3625?

real impressive if currently good wolfdales can go 4ghz with < 1.3v. hopefully will mean the more runtier ones will be able to do 4ghz at or below 1.36

probably scale close to 3.85-4.05ghz for 1.3625v for E8500 at least on average cpus

George nice job as always, still benching with the Blitz Formula? I thought you would have a Blitz Extreme by now.

thanks.. yeah no Asus love lately - maybe scared of the amount of memory/divider performance related feedback I always provide LOL

no probs, sorry to hear about the E3110 Xeon

Bumping vcore higher at 1.7v and 1.725v bios set (1.664v and 1.696v windows idle) managed to pull of my personal best 1M and 32M times with the help of E8500

32M @4753Mhz at 1.664v


32M @4791Mhz at 1.696v


1M @4798Mhz at 1.696v

very nice results eva

[clon22]

Very Nice results!

[pippo369]

1,696V with liquid cooling?
I hope this is kill voltage for penryn with non subzero cooling.

[hausner]

Nice Eva2000! Can you run 3d06 with 4600mhz or more?

[giorgos th.]

oh oh oh cant wait cant wait cant wait....
very descent clocks regarding of the ambient....
lets see what my 740 will do (when it comes) at 7-8C ambient with water....

[eva2000]

thanks guys

haven't tried 3dmark yet just trying to find my super pi cpu max first

[antari]

eva, have you any idea what the "T" in the batch code on the box means?

[DFI pit bull]

Wow, i'm lost for words. This is a great chip, thanks for the post eva.
Just wondering if I should buy this one now or wait for a Yorkfield.

I'm in the same situation Should I get a E8500 or wait & get a Q9450?? The rig will be mainly used for gaming & DVD ripping/encoding. Any opinions would be appreciated. Will be clocking on air & running 4x1gb PC2-8500 on a P5K premium.

DVD encoding? Get a Quad for sure!

very same question was here, but I am pretty sure I have decided for myself. Is a york at lets say even 3.4 would botleneck any game? (even those that will not use all 4 cores?) - I dont think so... And then come all the advantages of a quad (encoding, snappier system?, potential advantages , future games)...

So here is the answer - Q9450 FTW

*I see also no sence for myself to go for dual, then quad etc... york straight away --> a lil overclock (3.4 or maybe up to 3.6)... next step 32nm chips most likely (maybe less fun, but also less money spent at the end --> which will have to go for a next gen GPU anyway)

sorry for a little off topic

[eva2000]

yeah for video encoding quad core would be better as long as your video encoding software is multi-thread/cpu supported... otherwise if software you use ain't then higher clocked dual core cpu would be better

[Gogeta]

These Penryns sure are amazing. The next couple of months will be interesting.

Thanks for the thorough testing as always, eva.

You're welcome

Started to play with my 2x 512MB HIS HD3850 IceQ3 Turbo Crossfire pair with their stock bioses so I can use ATI CCC to overclock both cards.

@715/909 Stock speeds



@783/1098 Oc'd speeds







Still looks like 3dmark06 is cpu limited unless you use quad core but 3dmark05 is nice nearly 30K!

More to come

[dogsx2]

How do these chips compare with the others as far as the WOW factor? They really seem like fun cpu's.

[eva2000]

wow factor is up there with when i first played with E6850 but sort of same old..same old if you already played with QX9650 although my QX9650 is a very bad oc'er compared to these E8500 Q740A493T i have!

E8500 @4616Mhz 3dmark06/05 no probs



Sooo close to 30K!

[Seer]

You got 19.4k on 3dmark06 with 3850s? That's impressive

[fragmasterMax]

eva2000-
those are some crazy results!!!
great job!
Is there any chance you can test this out with a bad axe2 mobo?

[aoch88]

Hmm, what's the stable setting? Something that could allow you to prime and use daily?

[THRASHER2]

SEXY SCORES!!!!!!!!!!

[Blacklash]

Nice results,



Wonder if one of those would work well in my IP35-E.

[Sav]

Nice Cpu
max fsb is 545 mhz?

[eva2000]

thanks guys

Closing in on 20k for dual core cpu below

badaxe2 don't have it heh

4000mhz at 1.28v prime95

Nice Cpu
max fsb is 545 mhz?

555FSB max validation, 547FSB 1M, 540FSB 4M, 535-538FSB 32M so fair all water cooled with CPU PLL 1.5v


Now did the pencil GPU volt mod on my HIS HD3850 cards, very hard to pencil ended up reducing card's stock resistance from 2.262k ohm to 1.938k ohm (1.294v 3D load) and other card from 2.258k ohm to 1.900k ohm (1.305v 3D load), so that cards do 810mhz and 823mhz GPU respectively by themselves.

Together in CF mode, 810Mhz GPU seems to be max which is up from default 789Mhz GPU, so a 21mhz GPU gain from some 2B lead magic
