TPU's Core i7 Overclocking and Feedback

[Thrackan]

We really do need more benches on the Giga i7 boards. I just got my UD5, but I'm waiting for my new DO chip to fire it up. One thing I can say is that the board is a tank. Easily the heaviest i7 board I've owned, and it's my 4th different board. Very well made, thick PCB.

W00t! Finally I can get some comparison material

It's 2oz copper... But I think only the UD5 and Extreme have it.

vdroop can be almost completely fixed by using load line calibration in BIOS.
vdrop is what I worry about on my Gig board.
In my case, CPU-Z idle voltage is ~97% of the voltage set in BIOS.

I don't think 97% is reasonable.
~0.020v

Nope, UD = Ultra Durable series, which, in the case of 1366 boards at least, means 2oz copper.
So UD5*, UD4* and UD3* should all be 2oz PCB's. My UD3R is at least.

I've tested on several voltages and vDrop ranging from 97.1% to 97.5%. It might be that the range I tested wasn't big enough yet as I was actually conducting another test at the same time, but these are my numbers on the UD3R:

1.25    BIOS 1.216 CPU-Z .034 difference = 97.28%
1.15    BIOS 1.120 CPU-Z .030 difference = 97.39%
1.05    BIOS 1.024 CPU-Z .026  difference = 97.52%
1.0375 BIOS 1.008 CPU-Z .0295 difference = 97.16%

I know this is just a small test, but I was actually testing to find the lowest voltage my CPU would run stock speeds on at that time.

Please note that the vDroop was almost not present. The idle/load voltages monitored in CPU-Z sometimes didn't change at all, sometimes small differences, but I didn't put that on paper.

EDIT: found some vDroop notes:

idle 1.216 load 1.200
idle 1.120 load 1.120 (no droop)
idle 1.024 load 1.008
idle 1.008 load 0.992

Hope this helps.

more tease...

 

[kid41212003]

Lower shader clock and only few more CPU MHz got you another ~200 GPU score.

Obviously CPU bottlenecked, HT should worth ~200MHz CPU clock (at least in my case), did you try running it with HT On?

 

[Fitseries3]

gets too hot with HT on. need too much volts too.

im just playing around today. no serious stuff. if i wanted to i could. i just dont feel like it.

im just toying with this ECS x58. it runs great.

For the heatkiller 3.0 lga1366 cpu block, what are the major difference between the one for 90 bucks and the one for 60 bucks, one looks like it is all copper, but that seems like it is it to me. I was also looking at the swifttech gtz for 70 bucks, it looks like a good one and saw some people here had/have one. But the heatkiller looks nicer, big difference in performance?
Also a quad fan rad too much for just cooling the i7, or it is fine? Not sure if I would be going overkill with that big rad.

 

[Fitseries3]

quad rad is great for i7.

the 90$ HK3 is all copper while the LT for $60 is copper base with a delrin top. both are same other than that.

no real need for the copper top unless you want that look.

 

[freaksavior]

Do you think those Slipsreams are better than the S-Flex? I'm going to pick up a hand full for my rad, maybe the 1600rmp versions.

I dont know. i haven't had the others. i don think that these are loud.

Scythe SY1225SL12SH 120mm "Slipstream" Case Fan - Retail

i cant hear them over the rest of the fans i got.

 

[Chicken Patty]

Man CP that's rig is beautiful and I truly mean it looks great.





Hey just a FYI I have noticed with my new vista ultimate install my overclocking is not as stable as it was with XP. I can easily break 4.0 ghz still but it's not as easy as XP was.

thanks dude, Means a lot

I dont know if you saw my cooling thread, it has lotta more pics, check the last pages.

i'll tease up 40k a few more times till i show ya the real deal...

how dare you tease us like that!

 

[freaksavior]

does my temps seem about right? ambient is 72-74f

where did you post your temps?

 

[Binge]

For anyone with a DFI UT. Do this fix ASAP.

I'm not sure how it is with other motherboards but the difference this made on my DFI is crazy. Stability and speed are the main differences. I can get lower voltages on my DRAM and the DRAM can work at tighter timings. Going to try for a max OC now.

 

[Thrackan]

Did you turn 5VSB on or off?

 

[Binge]

ON There'd be no reason to change it from default otherwise.

The Biostar is good, though I don't care for the bios, and mine didn't handle high speed memory very well.

I'd say get the Giga...

yeah, thanks, I had pretty much come to that conclusion, my only real experience of gigabyte was my old x38 DQ6 which was just about one of the best boards I have ever owned, as you have the 5 I will get the UD4P as I dont need ESata and we can run a few benches, I will order mine this weekend, should be here by mid week

 

[freaksavior]

mugen 2, 2 x scythe slipstream 110cfm fans.

9 rosewill 75cfm fans.

i7 @ stock 40c idle.

im just thinking 40c idle @ stock is a bit high for the cooler...

hey tatty have you noticed 3gb on vista is not snappy unless you close some programs

 

[Fitseries3]

anyone have a few 6pin pcie connectors i can have?

bro these chips run really hot bro, at 4ghz 1.32v, I idle at just under 40ºc. I am on water, go figure.

 

[Jakethesnake011]

Hey I was wondering if I can get some input. I think I found my CPU block and my radiator that I might use, wanted some opinions on what you think of performance. CPU Block Rad
I also might be getting a d0 soon, I heard those have more heat out, but I might be able to get a high oc without the heat being too bad.

 

[dark2099]

Good choice for both for both block and rad, what fans are you going to get? I just got my D0, and its OCs better than my C0 did and better than the 940 I have too. Temps are better since I'm at lower volts anyway.

 

[PaulieG]

You mean 6 pin psu pci-e adapters? PM me your addy, and I'll get a few out to you. Just pay the shipping.

Really? I've never noticed that.
