TPU's Core i7 Overclocking and Feedback

whats the better way to mount a DHT cooler on an I7? East-West (like i currently have) or North-South?

 

[t_ski]

I like to orient the pipes (or ridges in a waterblock) so that they get the most contact with the actual CPU core (not the IHS). On an i7, the core runs longways in the same direction as the LGA socket cover and lever. Now, I can imagine that this orientation may be different on most boards, but if this is your board:

...then that means the core runs up and down. That would mean the pipes should run in the opposite direction, or front to back. I would install the heatsink so the fan blows upwards toward the top of the case, as long as it does not interfere with your ram. If it does, then you can only install it so the fan blows toward the back of the case.

I hope you don't have a 3 pipe DHT. Only 1 pipe will lay over the die while the other 2 are just outside of it. I'm of the (untested) opinion that 4 pipe DHT will perform a lot better than 3 since 2 of the pipes will lay over the die compared to 1. I had a 10C spread from coldest to warmest with my V2. Now with the NH-D14, my spread is half that. No lapping on anything either.

BTW, after about 4 reseats and tests, I found best temperatures by applying a small thin layer of TIM in between the pipes on my V2.

 

[FilipM]

Mine is with 4 heatpies, and i tested whats the best way with the CM paste that they give out, applying it between the pipes, put it on and wiggle around creates the best contact

 

[FilipM]

OK, ive put the cooler North-South and temps are pretty much the same

 

[Chicken Patty]

Didn't loose the touch over a month or two Voltage is a lot higher than it should be, I just don't feel like restarting now. Going to bed!

 

[FilipM]

Ok, ive reseated the cooler again, temps are lower by like 3C on core 0, 2 deg on core 1, the rest are ~1C lower.

I've turned LLC off, and put the voltage up to 1.36875 (1.288 in load) for about an hour, i turned it back on and now it runs at 1.288V in load no problem. Tested 5 runs in IBT on high, runs fine.


Also, I tried pushing the ram with teh cpu down, got ram stable up to 1800MHz on Cas9


Now runing 1520 @ 7-8-7-20-1T




PS. Where did you get that wallpaper from?

Here you go

Reet, i wanna hit 4.1GHz but didnt seem to be able to do it with what i tried:

Here's what im runing atm:

---------------------------
21 Multi

BCLK - 190
RAM - 1523 (7-8-7-20 1T)
UCLK - 3237 (2 x ram + 1)
QPI - 6857
---------------------------
CPU Voltage - 1.29375V
CPU PLL - Auto
QPI - 1.26250V
IOH - 1.14V
ICH - 1.2V
DRAM - 1.62V
LLC Eneabled


Any suggestions

I have mine set at 1.15v but not all systems are the same.

need help getting past BCLK 225+

Try uping you PCI-E lane to 101-102- and so on
Also try a windows program like easy tune or eleet tuner to increase your bclock speed past 225.

Try these if your temps can handle it.
If thats your qpi link speed in cpu-z its way to high.

 

[FilipM]

Thats my QPI Link in the bios, it is half of that in CPU-z. I will try those for 4.1, even though i think more vcore will be needed

 

[Chicken Patty]

Filip, give that a go. We can only suggest certain settings but only you can know what makes the system stable. My point is don't be scared to use more vcore. As long as you stay under 1.45v and your temps under 80 Celsius you are fine. Good luck

 

[FilipM]

Bah, i give up for now, ~1.3V and 4GHz for now, im too tired, lol. I can feel a cpu change is comming soon

 

[Fitseries3]

need help getting past BCLK 225+

110-115 pcie.

1.3 IOH

 

[Fitseries3]

anyone want a x5650?

 

[Chicken Patty]

Bah, i give up for now, ~1.3V and 4GHz for now, im too tired, lol. I can feel a cpu change is comming soon

Give it a shot some other time man take a rest and enjoy the rig for now.

 

[DOM]

110-115 pcie.

1.3 IOH

tryed it the QPI Link Data Rate doesnt like to be to high only gets past 225 with it in slow mode

 

[FilipM]

225?!?! pfff, i cant get mine to boot at 210

 

[Fitseries3]

i bench at 232

just need the right settings.

 

[Binge]

I'm glad the PCI-E trick got you past the 220 wall.

 

[DOM]

Yeah 110-115 works, but now im stuck at 225 , if i dont set the QPI Link Data Rate to slow mode no post

got it to post in the bios at 5GHz but need still working on getting it tuned to post in windows
