My retail 45nm Wolfdales - E8200 + E8400

[trans am]

As long as the new quads (Q9450 really) see 3.6Ghz+ on air, Im all over it.

I was just thinking the same. Before it was like wow if the dual cores are hitting 4.5ghz theres no reason for quad. but in reality if they are both hitting around the same clocks then take the 2 extra cores and 6mb more L2 cache.

I want some retail Yorkfield results

[godsfist]

You wont like the heat if the silicon doesn't get better

[fireice2]

I though these processors were much cooler than the conroes..

[Zeus]

Oh noes!

I had so high hopes on these.

Dinos said that all the guys in down under all did 4GHz Prime with 1.25-1.3V on these, some even primed at 4.5GHz.

Has got to be a different batch that's coming to europe.

ORB, where did you get these?

[syne_24]

I hope it isn't all ES hype and better batches soon to come. I was really expecting 4ghz stable as well.

[trans am]

I though these processors were much cooler than the conroes..

They do on stock volts but as every process gets smaller you increase voltage they get extremely hot. thats like 1.5v in 45nm is going to heat like 1.7v in 65nm

[OBR]

I have QX9650 quad what is orthos stable 4GHz without problems ... but it is ES! These first retail 45 chips seems like first Conroes, the same OC and Temps ... we need improved batches and next better series for higher OC. These first wolfdales are not so special ... and good.

[Xvys]

I wouldn't jump to conclusions until we get corroberative evidence. Intel may have just sent some binned duds to Russia to get rid of them. No offence, but testing them "under water" with a modded ps and load line calibration issues? Let's reserve our judgement until more results come in.

[GFORCE100]

I would wait for D0 stepping to come out, it will because the C0 contains errata in the Intel spec specification PDF with a "Plan Fix" next to it.

[Origin_Unknown]

i'd like to see an e8500 test

I was just thinking the same. Before it was like wow if the dual cores are hitting 4.5ghz theres no reason for quad. but in reality if they are both hitting around the same clocks then take the 2 extra cores and 6mb more L2 cache.

yeah, im thinking the exact same thing now

[AriciU]

Here's some 8500 stuff. Not mine. It was on air with the Noctua cooler if i'm not mistaken. The guy just started to put it trough some Orthos so it's not gonna stop at 4.2ghz for sure Low volts for that freq anyway.

[NightRaven]

hmmm weird... maybe cuz they were Q as well? perhaps L will do better.. but thats just a guess.

i do think we cant compare these with a qx9650 even though its quad and does better... its just different...

my 9650 does 4ghz easy easy too 1.4V to 1.5v or so.. but it costs 4x the price of one of these so we'll just wait and see

add: its retail not es

[trans am]

Could it be the e8500 is the one that they bin the highest and there is a huge gap between the lower cpu's? maybe there is a reason the chips cost $80 more than the e8400 and it wasn't just for that .5 multi it's highest binned so = highest overclock? Maybe I'm just blowing smoke but it sorta makes sense. Intel could be getting very strict with their binning of chips.

[AriciU]

Coolaler did 4ghz @ 1.256v and max was 4851 @ 1.59v. On air btw. Screenshots on his forum (in the Intel section). E8500 retail.

[flopper]

My first conroe e6600 did around 3.2hz 24/7.
My current e6750 runs 3.8ghz without problems.

Lets hope they get better since 4.5ghz seems to be a reason to upgrade but 4ghz isnt

[adamsleath]

bummer; even less contemplating e8xxx now

these results sound just like e6750/6850 to me.

more propaganda for e8500.
coolalers chips are sooooooooooooooooooooo cherry picked.

but also slightly better clock for clock , more cache and less heat....
if i didnt already have a c2d i'd take my chances with an e8400.

...as for yorkfields; they should all be given higher multipliers to make up for their 'poor' fsb ability....which generally for quads is lower than duallies...or is that too sane?

harhar; if this is any indication of yorkfield perf then 9300/9450 will probably suck a$$ in the fsb department.

more propaganda for the q6600. (& watercooling )

[eva2000]

Coolaler did 4ghz @ 1.256v and max was 4851 @ 1.59v. On air btw. Screenshots on his forum (in the Intel section). E8500 retail.

alot of it has to do with actual environmental temps.. coolaler's results you see cpu idle temps between 29-35C even at 4800+mhz on air... i can't get those temps even on water cause my room ambients between 26-34C these days heh

I got 2x E8500 Q740A493T cpus one does 4000mhz at 1.28v and other at 1.304v prime95 but on Dtek Fuzion H20 cooling.

This is the better of the 2 cpus I have 10-15FSB higher max FSB than other

Super Pi 1M = 9.953s @4638Mhz - 8.5 x 545FSB



Super Pi 32M = 10m 13.625s @4547Mhz - 8.5 x 535FSB

This set of 2x1GB Crucial Ballistix Tracer PC2-8500 didn't like 32M with tigher than tRAS 9 much, so might try a different set later. But 32M time seems a bit slow heh.



Wprime v1.55 32M & 1024M @4547Mhz - 8.5 x 535FSB

[S1mon-]

Nice testing Eva

[Sentential]

Im not suprised, we saw the same exact thing when Preseler was about to be released. Plenty of people with ESs got over 5ghz, and how much did mine do? 4.15.

Its just more of the same to be honest, if it is what I suspect (average of 3.6~3.8) that will re-affirm my decision to wait for Nehelm

"Now let’s move on to the most interesting part of our test session: Wolfdale overclocking experiments. We pin a lot of hopes on the new CPUs from this stand point, because 45nm technology and some other features, such as lower heat dissipation, allow us to expect the new processors to hit frequencies unattainable for the previous Core 2 Duo models.

We used the same test platform for our overclocking experiments as we did for our performance tests. The CPUs were cooled down with Zalman CNPS9700 LED cooler. The CPU stability during overclocking was tested with a 30-minute run of Prime95 25.5 utility.

First of all we tried overclocking our Core 2 Duo E8500 sample without raising its Vcore. In this case the CPU ran stably at 3.66GHz frequency.



Of course, it is a very good result. Core 2 Duo on 65nm cores could reach these frequencies only at increased Vcore. However, we wouldn’t stop here and continued our tests with increased core voltage setting.

Actually, our tests showed that Wolfdale responds very good to Vcore increase. But we didn’t aim for record-breaking speeds, so we only increased the processor Vcore in the BIOS Setup to 1.5V that resulted into the actual 1.42-1.46V taking into account Vdroop. This voltage increase is relatively harmless for a processor using an efficient air cooler and is acceptable for systems running 24/7. However, even in this case our Core 2 Duo E8500 didn’t disappoint us at all.

We managed to get this processor to run stably at 4.37GHz. No doubt: Wolfdale CPUs will become another overclockers’ favorite, because Conroe processors could hardly hit these speeds at extremely high voltages and with special cooing systems involved. By the way, our processor running at 4.37GHz retained quite acceptable thermal mode of only 70°C under workload.

All the above described experiments were performed without changing the clock frequency multiplier: it remained at 9.5x in all cases. That is why the maximum FSB frequency in previous experiments remained 460MHz. However, it would also be interesting to see how well Wolfdale processors can cope with high bus speeds. Therefore, we performed another experiment aimed at finding the maximum FSB frequency for our CPU, i.e. its FSB Wall.

As we found out, the maximum FSB speed for our processor was 540MHz. After that the system would lose stability. So, we can state the new processors have pretty high FSB Wall.

However, great Core 2 Duo E8500 overclocking results were slightly shadowed by the less impressive performance of the youngest model – Core 2 Duo E8200. Our Core 2 Duo E8200 test sample could only work at 3.2GHs at its nominal Vcore setting.

By raising Vcore we could hit higher frequency, but stalled at only 3.88GHz.

Of course, this is not a bad result at all, but nevertheless, Core 2 Duo E8200 yielded significantly to its elder brother, Core 2 Duo E8500. So, it turns out that Wolfdale overclocking success depends a lot on the CPU sample

[Chewbenator]

So it seems that the clocks are all over the place, as expected. There were alot of great Conroes out of the group that were there during release week. My e6400 can barely do 3.2Ghz stable, others even with the same batch number could hit 3.6-3.8. The really bad clockers came around about two months after release and some couldn't get 3.0. I don't think that the Conroes at launch were that much worse clockers than the ESs. 3.8Ghz for a processor that has better performance per clock isn't that bad.

[Speederlander]

This is what happens when people buy the first chips off the line. Let them get their process and QC in order and have some incremental improvement then jump in. Always wait at least 2 months from first general release if you are getting a permanent CPU. Longer is better.

[Glow9]

What does es mean?

[godsfist]

3rd one will do 4GHz like the others but requires too much voltage and isn't what I'd call 24/7 stable

3.6GHz on very little voltage is the sweet spot by the looks of it

[Kain665]

OP: Notice the stepping on that first chip is SLAPP... hm...
