TPU's Core i7 Overclocking and Feedback

Right now its @ 3.78 with turbo

i lost 10c off just by changing the fans
on load i hit 73C

There is a 4c diff between core 1 and 4 always

I noticed difference between cores as well, could be a mounting issue but I mounted my block in all 4 possible positions multiple times.
Might be a load balancing issue (running XP x64).

i have vista 64

so it could be 64bit ?

Should i turn off turbo when overclocking?
 
You aren't going to get flat temps across an i7 because of how the chip is affixed to the IHS. All of the solder carries the heat from all of the cores so some will have different heat than others because the cores are all sharing the same solder that connects the cores to the IHS and if you watch the core activity you'll notice one core jump and do some work... then another core etc etc. The most level chip I had had temps like 30 30 35 30. The one I have right now is more like 32 29 33 27. These examples were taken at different times in the past 4 months but I hope you get the idea. It's such a minor detail, but it is interesting eh Assassin?
 
I don't think he said or intended that at all.

Not necessarily my intention, no, but I was looking for far fetched reasons to explain the temp difference.

ah ok

going to try to push it a little more before i run boinc
 
Just keep in mind that you can expect to go to 80C+ on air and it isn't exactly torture for the chip, but still be careful in how long you OC something when it reaches those temperatures.
 
i will be happy with 3.8, right now i have it at 3.78 so i will bump bclk a few
 
Been running 21*183 for ages on my C0 and I have to say that if you can't get that stable, your chip sucks ;)

If you want lower temps you could turn off HT, saved me an average of 10C. I don't know how well BOINC handles HT but most applications I use don't use it (very well) anyway.

i see you have the same board as me the UD3
do you like this board?

My UD3 exploded :D but that was entirely my fault. I have a UD5 now.

Gotta say the UD3 is very decent for its price. Good BIOS (imho) and decent layout.

The only things I didn't like were the heatsinks on the NB and vregs. They got extremely hot, but I don't have an exceptionally high airflow near that area. Using an air cooler might help there.

I have a few fans blowing across the whole board

lol you have my second board too
:roll:

how you like that one ?
 
Lol, the UD5 is basically the UD3 with some extras. Quality build overall.
 
Hi all
got my new i7 build:
Gigabyte ex58 UD5
i7 920 D0
6gb patriot 1600mhz
750W PC Power & Cooling PSU

<-- rest of details to the left

it's currntly at 4.1, HT and turbo both enabled. I'm using. Pretty low voltage and CPU-Z shows it as 1.184v under load. Temps peak into mid 80s after a few hours of Prime but in reality no video encoding or gaming is going to make it that hot.

I'm wondering what the next step is. Since my voltages are so low I'm sure my chip can go faster but the temps are a bit of an issue IMO. Should I disable HT?
 
I would suggest overclocking only until you notice your computer is running smooth as silk. For me the magic # is 4.2GHz, and others use 3.6GHz. Really I've run it at stock and done wonderfully. If you can run 4.1GHz at below stock you can save yourself the extra cost of electricity by keeping that wonderful 55% overclock. Think about it... stock is 2.66Ghz and you're at 4.1GHz without making your chip really work for it. Do you want to break records or do you want to have one of these magic chips for more regular use? I'd assume if you bench, just bench with your daily settings and compare it to what people are busting their balls to get. Honestly pushing the 920s beyond 4.4GHz is a task in itself which is on a completely separate level from getting it to 4.0Ghz. I'm getting to be conservative now because I think I've explored as much as I would like to explore with respect to the chip, but my curiosity keeps me learning enough. In summary I'm happy with my easy daily OC. Are you happy with yours?
 
im never happy with my OCs. more is better no matter how high you get :D

thats just me though
 
You so crazy Fitseries :p

To be honest yes I'm happy but I guess curiosity wants to know how far I can push the chip bat the end of the day almost nobody *needs* an i7, even at stock speeds. It's more of a hobby/enthusiast thing right? Most games are bottlenecked by GPU (definitely the case for my system) and there haven't been any games to really push gaming PCs since crysis warhead.

So yes I could leave it be and just tweak memory speeds, timings etc to try and get the best out of my hardware. Hmm.. just my 0.02c anyway
 
I assumed that's what you were saying, but if you look closely I'm just saying... even as a hobby. OCing much further than what you get easily is a PITA with the i7. You may even waste money buying different mobos/memory because that can be the issue holding you back. Your chip is very important as well, but other components can cause weak OCs. Ahhh it sounds like you made up your mind. Why ask if I'm going to end up just getting your $0.02 in hobbyist logic?

At the end of the day I do use my i7, but I fold... sometimes crunch, edit 3D, game, and encode/edit video. I guess for you it's OC or just sell the thing, right?

No I haven't totally made up my mind and to be honest, this is the first chip I've really overclocked. I'm happy with 4.1Ghz, but if I could get 4.2Ghz easily then I would do it. I do know what you mean about the money wasting though.. I see people all the time upgrading motherboard so they can overclock more and tons of other things I would never do.

My point about "using" the i7 fully: for gaming, it isn't vastly better than anything else, especially since graphics cards are the bottleneck now, even for nippy C2Ds, let alone 4+ Ghz quads. Video encoding, photoshop, 3d work etc fair enough, but unless you're doing it a LOT or you are paid to do it, saving a couple minutes isn't such a huge issue. And let's face it, the whole reason this section of the forum exists is for enthusiasts :D It's a normal, natural thing to want to weak and fiddle. People like fast cars when you can only drive the maximum speed limit and even accelerating at the cars maximum potential will probably get you a ticket for dangerous driving.

It's not just hobbyist logic. I'm happy with my o/c and computer performance, but if I can easily get more, I would like to do that. If not, then I'll leave things and stay happy with my new computer.
 
Good! So we're on the same track. Easily you can get this to do 4.4Ghz like I said above. Then the problems start. If you're on air I wouldn't press your luck though ;) The temps might become a chip killer even under 50% load.
 
Hopefully I will have some results before Thursday. Waiting for the last 3 items to arrive before I go johnny5 al1v3 on the i7 build.
 
Just got my UD5 installed and ready to go, I will post some overclocking results.

Binge you were right my balls exploded with the amount BIOS options.
