Core i7 Overclocking by Batch #

[roller11]

Very nice Overclocking.
But... does someone has a D0 with the batch 3849Bxxx??

yes, 3849B016 5299.73 Mhz on dry ice, good for 7th place ranking on HWbot

Great so!
Because maybe I will get one of those with a DFI UT x58.
So I wana see if wait it would be worthy.

Thanks

[roller11]

Don't wait too long, the early batches generally OC better than the later ones.

Anyone else has result from batch 3844A717??

I have the same batch and I have no clue how to OC yet with the eVGA X58 Micro... But I have mine at 3.6GHz so far with no voltage increase. What's messed up is that CPU-Z shows the voltage at 1.18v and flucturates up to 1.20v. Been running prime for only 40 minutes so far. Idle temps are 38 - 41c ... With loads of Prime 95 showing 65-68c on all cores with a TRUE 120 BLACK with a 120mm fan connected to the motherboard. Can't figure out how to run the fan faster yet either. You can't even fricken here the fan and the TRUE is slightly warm all around.

Once I figure out what voltages and all the fun stuff then I'll crank it higher.

Picked mine up in Westmont at MicroCenter...

I wonder if there is a 3849B001 batch out there somewhere.

I got that CPU's neighbor, I picked up a 3849B018.

This is my first i7, so i need to do a lot of reading to catch up.

so far on my EVGA Classified i have it at 3.80GHz with 1.21 VCORE. everything else stock.

will update with more results late.

I have a "simple" question..

what is the best batch of 920 D0?

Batch 3844A717

What ram are you running? Did you change the ram settings in the bios?

I have a x58 micro and I cant get my proc to go over 3ghz on the stock voltages.

When I first tried overclocking the computer wouldn't even boot up. My monitor would be in sleep mode. So I reset the CMOS and started over and upped the BCLK to a modest 150 first. Then I set the UNCORE multiplyer to X17. For some reason this setting is important. Don't have a clue why. lol

Then I changed my memory to the lowest setting. I think it's a 8:2 divider (800MHZ). Didn't touch the voltages at all. I saved the profile and rebooted. The PC finally booted up. Then I went back in and altered the BCLK again too 182 and changed the voltage to 1.275 (VCORE) and it booted up again. Nothing else changed from before.

I would definitely start like that.

My memory is the Mushkin memory:

3845B027. This CPU clock, 5383.73 Mhz, is #1 on HWbot for both i7 920 and W3520.

How is it working the 3845B228?

Air cooling with a 780 RPM fan in a 85F room, I'm running 4.105 G, 24/7, full auto except I set Vdroop to disable

Wel Im not going to wait for it more than 1 or 2 weeks, because Im without Computer and Im very very near to madness

But also take in count that Im from Argentina and thing here doesnt come as fast as USA or Europe.
So... I have to wait or wait.

Thanks again

Just got my 920
SLBEJ
3910A418

See what it'll do later tonight.

So mine does:
bclk 200
cpu multi 20 + turbo mode = 21x
ram multi 6x
uncore multi 13x
QPI 36x

cpu vcore = 1.35
QPI vtt = 1.4
vdimm = 1.6


Hums right along.

I think the CPU cores have more to give, but if I try to go any higher on the QPI I lock up. This was verified by dropping th bclck and raising the QPI multiplier 3600mhz stable, 3700mhz locks on post, >3700mhz = no post.

Any ideas on getting more QPI, I'd hate to have a golden proc sitting in the slumming it because I cant' figure out how to get more QPI.

What mobo? and can you post some LinX stability screenshots?

[hetsaq]

Interested as well.

Is that a C0 or D0? Mine is a C0 and thats what it runs. I can get to 3.8GHz but no amount of vCPU will make it fully stable.

Been thinking about getting a D0, but if that is what you got, I am scared then.

[road-runner]

I got a 3849B018 today from microcenter, just got it going earlier on air. Seems to be a nice chip, doing WCG at 3.9Ghz with 1.24..

Hi Sotti,
My 920's batch 3910A311 ... almost the same
Because of room temp(30C-34C) I could not go high...
bclk 200
cpu multi 20 + turbo mode = OFF
ram multi 8x
uncore multi 18x
QPI 18x
cpu vcore = 1.215v(bios) win 1.28v
FSB vtt = 1.34
vdimm = 1.66
It has TRUE with fm121...
iddle 46C-51C
load 80C-86C

Try to Enable Turbo and use 191BCLK x 21, you will be able to use lower vcore and getting lower temp

Just recieved my 920 from newegg batch # 3904A361

Is this C0 or D0?

Thanks! D0 is the better OC's right?

Of course...where have you been all this time?

[TheCarLessDriven]

Been almost 2 years since I sold the rig in my siggy, bought a MacBook Pro from that for photography work so was out of the PC/custom world for a while. Now sold the MBP and now I just got al lmy stuff for an i7 rig, lol. I did about 3 weeks of research putting together my i7 rig.
