**Official e8400/e8500 Retail OC Thread

[LagunaX]

Hey guys, quick input b4 I bite the bullet.

My three e8400 choices: Q814A014, Q817A472, and Q817A473.

I know the q814 is a known 4.1-4.3ghz performer.

Any news on the q817a's?

I have an unopened q807a091 e3110 in the box but the q814 seems to have a higher ceiling...to e3110 ebay you go!

[Xvys]

Can someone help me overclock a nice E8500, not common this chip, this is what I have: http://valid.x86-secret.com/show_oc.php?id=384956

You could go to a 400 FSB, which will raise the cpu to 3.8 GHz.

Cpu voltage should be raised to 1.3v and Ram voltage to 2.1v for testing. All other bios settings should be ok on AUTO.

Your system should be able to run comfortably at 4.0 GHz with the maximum cpu voltage 1.3625v or less.

I want that Xeon 3110 !!!! why on earth wouldn't you ?

[Garrett]

Exactly Leeghoofd, I have a Q751A439 Xeon E3110 that does 4.2ghz @ 1.33v 24/7... not too shabby right?
I'd say give that Xeon a go and then maybe...... sell it

[plion]

Hey guys, got 3 questions, sorry for the noobness:

1. Can someone tell me which is the correct fsb strap setting for 1:1?
On auto the dram freq option is ddr2-801. On 400mhz fsbstrap it is ddr2-800.

2. I want to stay at 3.6ghz 1:1fsb/dram, what should I do next? Lower performance level and run memtest and/or prime?

3. Pci-e freq: 101 or 100? Not really sure anymore.

system:
Asus P5Q Pro / E8400 @ 3600MHz
2x2 GB G.skill DDR2-800 5-5-5-15

For ya voltages AUTO really overvolts : Set CPU PLL mate to 1.52 - FSB Term voltage to 1.26 - NB Voltage to 1.26 - Drop performance level to 10... rest looks okay..

[affiliate13]

Got an E3110 Q802A this afternoon, i have been trying to get info on this batch other than the E8400 logs in leeghoofd's wolfdale list (which has been very useful thanks).

Has anyone got a Xeon from this batch? ta.

[roger_h99.nor]

Yes. Had one Q802. Bad chip - sold it.
It barely broke 4Ghz Prime at Vcore 1.425.

Yikes! I'll drop it in and see where it goes. Lol im gutted before i start.

I've got my performance level on 7 should i increase to 10 ? i can't get my system stable at 4.0ghz (FSB 445x9) .. only with 430x9..

[zlojack]

^^Those sticks should be able to run at PL=7 at 450FSB.

[faria]

the problem is my cpu! i left to many days cpu ppl and fsb voltage in auto with 445FSB!

My response was too Plion mate who runs a P45 based chipset mobo. 1:1 divider is PL 9 lowest there... at 400FSB/800MHz

Hi ppl, this batch is good? ...

Q813A190, i want to buy it, tell me something of this FPO...

[C-N]

Small update for your OC list Leeghoofd

Same spec setup as my last post http://www.xtremesystems.org/forums/...postcount=3566 just 1.28v load @ 4.2GHZ 10H Prime blend stable.

CN.

[Leeghoofd]

Added mate, thx, dunno if I added this but my lapped Q805A546 rocks now 4ghz 8 x 500 at 1.216 Vcore I just had to drop PLL to 1.52 and FSB Term to 1.22 and it would allow me to drop Vcore too...

[So3oL4Nu]

Hi ppl, this batch is good? ...

Q813A190, i want to buy it, tell me something of this FPO...

@ LEEGHOOFD...i use u're settings that you say (x9 425FSB), i use the next setting for x9 425FSB :

Dram 850mhz 4-4-4-12 Voltage 2.1 (Corsair XMS2 DHX)
Vcore 1.42 BIOS
NB 1.4

With this setting the system is stable, i run fast orthos for 2,3 minutes with SPI 32 at the same time..Vcore load is 1.368.

I tryed 4GHZ with this setting, the Vcore is insane i think...

9x
445FSB
Dram 890 4-4-4-12 Voltage 2.2 (Corsair XMS2 DHX)
Vcore 1.4750 BIOS / under load 1.37

Again i tested fast 3,4 minutes with SPI 32 at the same time...stable again...

I have a question, at a good batch that can do 4GHZ unde load with 1.25/1.3 what Vcore you need to set in bios ?

Sorry for the quality of the pictures but the 200kb limit is...

[So3oL4Nu]

I tryed the same settings at x8 with 500FSB and it worked...all the time i've have the impresion that my ram is not good...but the ram goes like hell...i can run 890 / 4-4-4-12 @ 2.1/2.2 voltage...the problem was the Vcore...this CPU whats more and more voltage...

[Leeghoofd]

Mmmm so3o4nu try to lower the vcore in small steps... if you can run 8 x 500 with the same Vcore setting then at 9 x 450 it would prolly needs a tiny bit less... and try small FFT's for CPU test... my rig is stable with small and Blend... but sometimes caps out at large FFT's... yet it is folding all the time, gamed upon , benched upon and it's rock stable there...

What PLL and FSB Term do you use ?

[HDCHOPPER]

thanks ! very good to know
eye keep getting higher clocks for less vtt & pll also but still at the same or higher cpu volts ..up to 4.5 cpu speed ( want to see 4.8 or better ) now & stable to me doing folding and surfing and all but ya larg fft are kinda funny some times go for hours & sometimes not good enough for me tho

eye tried 2 817 and thay were terrible.. hard to hit 3.8 at 1.368 v if eye rembember right 814 much better but eye would def. keep that 3110

Good luck with your Q814. I also had one and was not so good, 1.35v to boot at 4Ghz on P5K-E with vdrop mod, only SPi 1MB stable.
