well my new E8400 EO Q843A771 vid 1.23 is turning out to be a very good chip.
heres 9x473@4257 w/1.23v

[fatguy1992]

Ooo very nice Radaja So u had to sell that E3110?

[radaja]

yep i did and i wished i hadnt,but i needed money.but now its all good,was lucky enough to get a better cpu.thank you god

[fatguy1992]

Oh well, still thats a awesome CPU you have now

[radaja]

yea.even though the Xeon had a much lower vid 1.16 it neede 1.39 to do 9x500@4500. this new one only needs 1.32v to do 9x500@4500

[fatguy1992]

Very nice I wish I had that CPU under my phase change

[radaja]

i wish i had your phase change on my cpu
im going to have go WC for sure now,otherwise it wouldnt be fair to
this cpu.

[fatguy1992]

I was going to get WC, but it would cost $700 to $800 for a high end setup, my phase change only cost $1070. So for an extra $300 I get -50C temps, instead of 50C

[radaja]

that seems pretty steep for WC.im just going to get the 240$ kit from swiftech.
this is just an amazing cpu.9x458@4124 w/stock vcore 1.237v bios/1.216 cpuz load.


and 9x500@4500 w/1.32v cpuz load


and 9x514@4626 w/1.34v cpuz load

Have an e8400 that I got last year, ordered it shortly after they came out. Ran it at 4.05ghz for well over a year using LLC on a P5K Deluxe board.. Got a quad and a new motherboard earlier this year and had put it away until last week, was bored one night so I thought I would try it again using the Gigabyte board. No signs of degrading after 1yr+ using LLC and countless hour of Prime, IBT, and LinX. I think these chips are a lot harder to damage than some believe. You can see the date in Orthos, 1/23/08 in the first ss. The second ss was a LinX run I did last week in the EP45 UD3P board well over a year later.

BTW that's an awesome 8400 you got there radaja. 4.5ghz-1.328v

How does the newest batches clock?

[radaja]

well i cant speak to all newest batches or E8500-E8600's,but my new E8400 EO, OC's real well.
batch Q843A771 vid 1.237 bought it from newegg 3 1/2 weeks ago
just look in my sig,4500 w/1.32v is pretty good in my book.

On AC?

[radaja]

yep

[Dark-Energy]

Damn, you guys are freaking lucky.

In order to get my E0 running at 4500 MHZ, it takes above 1.412 volts. At 4.25 any lower than 1.328 will cause problems. And I bought it in late December. The batch number is Q832A389

Any tips to lower the voltage would be appreciated, I want to keep temps down, especially in this warm weather we are getting over here.

[fatguy1992]

Have you tried playing around with the MCH and CPU references? They have helped me run lower vcore before

[radaja]

9x500@4500 w/1.31v
i was able to lower my vcore by raising my vtt one notch for this run.
but theres only so much that can be done,the rest is up to the cpu.


fatguy1992 was right about the mch refyou really have to find sweetspot
well i switched my mch ref from 0.750 bios/0.700 ET6 to 0.770 bios/0.720 ET6
and was able to drop my vcore even lower.

Just fiddling around with my parents PC. I didn't realize that their P5Q Pro was rev A3.

[kuebk]

radaja - what mobo?

[fatguy1992]

Hes using a Gigabyte UD3R I think.

[Hughyhunter]

very impressive radaja

[Blue Storm]

last week I had quite new batch Q830A931 of E8500 E0 and it was bad pieceit was extra heating, because my Intel stock cooler is cooling my E5200 with 1.65V on 68°C Idle...but this E8500 on 1.28V had 90°C in BIOS and I didn't understand it...first step was with 1.4V, but after reboot was temperature in BIOS 125°Cis it normal with stock cooler? my last E8400 C0 was cooling with this stock cooler on 1.5V and temperatures weren't over 90°C

Cpuz does not read the .5 multi As you can see it only reads 9x multi.

Just update the bios to latest one and your problem should went away
