Overclocking an E3110

[Tullphan]

I've been doing some trading lately...traded my CM Stacker 832, MSI P45 Platinum, Q6700, 4 GB Corsair Dominator & a BFG 800W PSU for a 97 Grand Cherokee. To replace my Q6700, I traded a DFI LP UT P35 T2R for an E3110.
I thought i'd be ok. I've read where these things will do 4 Ghz standing on their head. Well, I guess my dumb luck came through again & I got one that won't.
In order for this thing to do 3.6 stable, I have to run it @ 425x8.5 & @ 1.3V (according to CPU-z). If I want to go 400x9, I have to bump the voltage up a notch or 2.
I'm using a P5Q motherboard & Mushkin DDR2-800 ram. The PSU is a Corsair 520HX.
It looks like this thing isn't going to do 4 Ghz w/o some serious voltage & i'm not going to risk that. According to this, the VID voltage range is 1.225V-0.956V. Is that different than the voltage i'm seeing in CPU-z?
Thanks!

fwiw: i recently traded a q6600 for an e3110 C0 also. on a gigabyte p35 mb it runs 450x9=4050mhz vcore 1.29@ load / 1.328 idle / and 1.35 in bios. (4gb ddr2 @900mhz 4 4 4 12) e3110 vid - 1.1875.

up your vcore a bit!

It's doing 425x8.5 @ 1.3v load.
I don't wanna get too crazy w/voltage for an overclock that'll not net much of anything.
I was just worried that the 1.3v might be too much for the Xeon after lookng at the specs on Intel's website.

Mine old one did 4GHz using 445x9 @ 1.33v an 475x8.5 @ 1.33v in bios.

That's it...rub it in! :disgust:

OR, i was simply giving you my input as a place to start. :roll:

I have one right now, except of an E0 stepping, and labled E8400.

it's at 478 x 9 1.39v. it's set to 1.48v in bios.

 

[Tullphan]

Just how much voltage can these things take safely on air?

I know...just kidding.

1.4v read from CPU-z

1.4V read from BIOS. When you come off load, the chip will see over 1.4v on the chip.

you sure about that?

what if you set 1.4 in bios, and it's 1.36 on the desktop, then 1.33 during load?

edit: anyways i guess the actual answer is the chip's rating, which is like ~ 1.3625v or so. It will say on the box

 

[Gillbot]

if it, 1.4 in bios then 1.36 on the desktop, you'd need to run 1.44 in bios to get around 1.4 on the desktop. That puts you OVER the recommended 1.4v already.

 

[Tullphan]

I bumped it up to 1.39xx in the bios & tried 500x8, 475x8.5 & 445x9. I bumped the ram timings to 5-5-5-15 & 2.1v. It wouldn't even boot to the desktop.
Now I guess I need to figure out if it's the motherboard (P5Q Pro), ram (Mushkin DDR2-800@5-4-4-12) or the chip.
If it's the motherboard, any other suggestions for one that'll do those FSB speeds?

 

[OCGuy]

P5Q, huh? Can you list your BIOS settings? ASUS has some crappy things like "Transaction Booster" that made me hit a wall @ 3.6 on my E8400 before I figured it out.

Also, anything 1.38-1.4v load is not going to ruin your chip faster then you will replace it (most likely).



What you put in BIOS doesnt matter. It is what CPUZ and other monitors detect is going to the chip. It is hard for a mobo to put the exact amount of power to a chip that you request.

OK...here goes:
Ai Overclock Tuner - Manual

Ai Clock Twister - Auto
Ai Transaction Booster - Auto
CPU Voltage - 1.31875 (CPU-z reports 1.288V @ idle)
CPU GTL Reference - Auto
CPU PLL Voltage - 1.52
FSB Termination Voltage 1.14
DRAM Voltage 1.80
NB Voltage 1.14
SB Voltage 1.10
PCIE SATA Voltage 1.50
Load Line Calibration - Enabled

CPU Clock Skew - Auto
NB Clock Skew - Auto
CPU Margin Enhancement - Performance Mode (Other options are "Optimized" & "Compatible")

You FSB Term (VTT) and Northbridge voltages may need a bump..


Also are you positive your DDR2 800 can run @ 851?

How much of a bump?

I wouldn't stake my life on it, but it ran the speeds i'm running now Prime95 stable for 24hrs & OCCT stable for over 8 hours. It also did 10 passes w/the Intel Burn Test w/no problems.

 

[Tullphan]

Would I be better off w/a different motherboard...perhaps a Gigabyte EP45-UD3P?
Is there a test that'll check the "guts" of the chip to make sure all the "internal" components are working as they should?

 

[Tullphan]

I bumped my voltage up to 1.4x, the FSB Termination voltage to 1.26, the ram to 1.9, the NB voltage to 1.4, the SB Voltage to 1.3, loosened my ram timings to 5-5-5-18 & it still won't run at either 475x8.5 or 445x9.
What's holding me back?
Since all DDR2-1066 is just overclocked DDR2-800, I don't see how it can be my ram. I thought the P5Q Pro was supposed to be a pretty good overclocking motherboard that could hit some high FSB numbers. The E3110 is basically an E8400 that's supposed to do 4.0 GHz in it's sleep. Could I have all 3 components bad or what?

Don't fall into the trap with an expected minimum oc. Many people fell for that with tha Q6600 G0 at 3.6 and MANY never got there.

Have you had that board over 450-475fsb yet? Drop your multi to 6x and see how high you can push the fsb, then slowly increase the multiplier.

 

[Markfw]

And 1066 is not just oveclocked ddr2-800, its certified to that, and many ddr2-800 don't do that.

 

[Tullphan]

Theoretically, how high can one push the FSB @ a 6x multiplier?

The highest I have gotten is ~525

HIGHLY depends on your components. I've had my MSI board north of 550fsb with an E8500 but my ram was getting VERY warm so I backed it down. I usually do two types of testing when I get a new chip. I set the multi at it's lowest (usually 6x) and see how far I can push the FSB. Then I raise the multi as high as I can and see what max speed I can get is. Then I tweak for max speed and FSB using a combo of both and see where I get my best performance.

My old E8500 topped out around 4.25GHz stable running at 501FSBx8.5 multi. It would do higher FSB's but it was hard on the board and ram and yielded no extra performance.
