Core i7 Overclocking by Batch #

**freshy** · 08-07-2009, 08:27 PM

4.3 @ 1.306 vcore
4.4 @ 1.337vcore, qpi/vtt 1.3v

is 80c max on worst core to much to be priming at ?

**Badge56** · 08-08-2009, 03:58 PM

Just got my I7 and mobo. Waiting for RAM.... Next week,,
batch 3910A300 What do you think?

I'd say fine till 85. I wouldn't recommend more. Your call, though.

Just got my I7 920 Batch #3910A379

I am 24-Hour Prime Stable at 3.6Ghz (180x20) 1.25v

I am testing 3.78 (Turbo on) .. You will notice on the screen shot that CPU-Z reads 1.16 ? I have it set in the bios to 1.25v. Anyone have any tips on keeping the CPU Voltage Regulator cool? It looks to be getting a little high.

I am getting some G.Skill Trident (2000Mhz) on Monday so I will see what the CPU can handle then.

My Setup is:
Intel DX58SO Smackover (Newest Bios)
Intel I7 920 D0 Stepping
Thermalright Ultra-120 eXtremee 1366
OCZ OCZP16006GK Rated for 7-7-7-20 DDR800 @ 1.7V | Running 7-7-7-24 720Mhz @ 1.58v
Antec 900

my batch is close to yours 3910A264, I was able to get 4GHz 191x21 stable with 1.280v under load in CPU-Z, I can pass linx 50 passes full memory with 1.264v but OCCT CPU needed 1.280v to pass 6 hours

3849A916

Running quite hot, even at low voltages. Testing it at 4.2 atm, seems to be running stable at 1.28vcore

**drewxbk** · 08-09-2009, 12:54 PM

also running hot on low voltage..3904A361

Water cooling heatkiller copper block, swiftech 3 x 120 radiator, 655 pump. vtt 1.3v. I dont remember what vcore was set on, classified board...

Scooby's 3849 batch (close to yours, but not exact) is a MONSTER on air. Does 4.5Ghz. Overall it seems the vast majority of 3849B chips are excellent clockers.

I guess I'm overdue in this thread.

3903A468| 5/15/2009| D0
P6T6 WS Revolution (Bios 0407)
3x2gb GSkill Pi (blue)
Vendetta 2 using 1600rpm Xiggy 120mm
HAF 932 with no fan changes
Enermax 85+ 1050w

Messing around with low volts.

24/7 overclock until I get a IFX-14 to keep temps down at higher vcore needed for 21x200. I've got 3600 uncore stable with 1.325 vvt and lower vdimm to 1.6. Just need to get a pic of it. Will happen tomorrow.

I just got a replacement chip sent out which is batch 3910A501, I was wondering if anyone here knew if these were decent clockers or not?

My last chip was a bit of a dog tbh, it was 3851A228... I hope to god that this one is better!!!

You batch is mighty close to mine.. I have a DX58SO and can do 3.78 at 1.23 Vcore prime stable for 24 hours.. I just got a Gigabyte UD5 to replace the DX58SO so I will see how that goes.. My batch is #3910A379, either the board is limiting my overclocks or these chips IMC's don't clock well.. I can boot into windows at 4Ghz but nothing is stable..

**Geebs** · 08-14-2009, 06:53 AM

Sorry for double posts, but this seems to be the more active thread...

I just received from Intel this am, a 3911A207 batch 920... anyone have any insight on this batch? I can't seem to find too much info on it???

**barrymaldon** · 08-14-2009, 01:11 PM

Will be very interested in this, I have a 3911A200 so should be very similar chips (also running a P6T Deluxe but V2)

So I take it you haven't set it up yet? I just installed mine, typing this at stock speeds and voltages... gonna check and see if all is stable before I start tweakin

**JaredC01** · 08-14-2009, 01:45 PM

So what's the general analysis on the 3910 batches? I've got a 3910A301 920, but I'm waiting on RAM and a few video cards before I can test it.

Based on what some people have posted, they clock OKAY, but not as good as the 38XX, correct?

**barrymaldon** · 08-14-2009, 01:53 PM

Not yet. still waiting on the Heatkiller WB. Only have a stock heatsink atm so no point until the waterblock arrives

batch#3910A308 i7 920
4.0ghz@1.275v
4.2ghz@1.375v
Will prove later

**barrymaldon** · 08-14-2009, 02:15 PM

what cooling are you using (and temps please

)? and is that 24/7 stable?

Swiftech Apogee GTZ waterblock and the MCR320 radiator as a cooling. The coolant is water+p5 nuke. It's 45minutes IBT stable and 8 hours pime95 small ffts stable. I don't run my system 24/7...
As for temps it is within 73C under prime when @4.0Ghz and 85C when @4.2ghz. Pics that prove 8+hours stable I will post another time.
