i7 860 back from RMA horrible Temps and OCability..?

post #1 of 11
Thread Starter 
I got my 860 back two months ago after it fried and recieved a new one. Now I'm not sure if intel reached to bottom of the box on this one and just handed me worst CPU they had. Or if something else is at hand.

With my new cooler I recieved, Coolit Vantage ALC, and I'm 90% sure its fit properly having reseated it a couple time. But having tried a OC at 1.17VC (stock is 1.11250), produced near instant temps in high 60's which climbed into the 70's before it failed LinX. This was only a 3.6 Ghz OC... not much compared to the ease it was for me to OC my last chip to 4.0 or 3.8 (1.22, which didn't even allow this chip to enter windows at.)

So;

A. Regardless this Chip is just a poor OC'r that I can tell that it won't even boot at my previous chips stable OC.

B. Now The High temps may be to blame on the Heatsink? One of the arms on the mounting bracket did break off, Thank you Plastic Arms... I glued back together more or less unsuccessfully as it only flops around now. Though this shouldn't highly affect how the cooler is seated since the bracket is still essentially in the same position? and still tightened down. On Stock setting under LinX burn getting 59C at load

________________

Now I know putting the intel heatsink back on and giving it a whirl would be the answer to whether heat is CPU/Heatsink related, but I am more concerned about the much more important Why the hell aren't you overclocking. It even failed a minor bump from 133 to 140 /w turbo turned off.

So this is and seriously wanting to Tri-fire for BF3 is making me want to buy into Bulldozer on its soon release since I have 330$ instore credit for a recently returned 5870 that died =\\, Should be enough to get me a CPU etc. My main concern isn't flexing my Benchmark muscles but in-game performance and if bulldozer can deliver that I'm onboard.

Oh and would there be a significant difference between my 2.8 (turbo) and 3.8 or 3.6( not that I can even achieve it) in Fps?

My guess is the main culprit for the lack of OCing headroom is the cooling. 60°C on stock is just too much, you can't extract much of anything out of this chip before hitting 70°C even if you don't overvolt. The cooler should be better than that, so my guess is that either it's not working properly or it isn't well installed.
Anyway, my 2 cents: until you drop stock temp to some 45°C you shouldn't bother trying to OC as high as 3.6GHz; check if the cooler is well installed, if the pump works, if the tubes aren't strangled, etc. For gaming, even in Tri-Fire the 2.8 to 3.6 GHz delta shouldn't make much of a difference. If you plan on benching you may loose as much as 5% FPS, but compared to the risk of toasting the CPU that's a reasonable loss.

How did you fry your previous CPU?
post #4 of 11
Try to push the vcore some more. I'm running 1.37v for 3.8gHz so it's possible that you just got a bad clocker. Temps wise I'd start worrying if the chip goes near 90C in IBT/Prime/linx

I was more or less just wondering about Gaming, I gave up already on OCN fever of needing to flex my nerd muscles. Though playing a game in Eyefinity at High Fps is something that does matter to me.

My cooler can't handle those voltages even 1.22 is just a no no. As long as I'm not experiencing a high bottleneck on my current graphics cards I can stomach it for now.

Previous CPU was fried from Mobo trace burning out, wasn't physically damaged, just burned out for some unknown reason taking the CPU and a stick of RAM with it. Sorta lit on fire.. lol... Asus and Intel( I thought) were good about it. I just know this chip isn't OC'n close to what my last one was.

This one didn't even boot at the 3600mhz at 1.22 =\\, and given that temps were far to high again.

Stock Idle temps look solid mind you, about 28C.

I had an i7 860 that was a pretty sub par clocker too. I guess most of the earlier ones were. If you are using it for a gaming rig I would honestly disable hyper threading. It will help with temps and clocks without hurting performance in most cases.

Your temps are more than fine. You don't have to stay under 70C, Intel chips can take a beating so even 80+ is just fine if you feel comfortable with it. The chip isn't going to die with those temps anytime soon. Personally I'm not going to run this one for 10+ years so I don't really mind.

I'm going to reseat it tonight maybe I'm not satisfied with the temps something is up, this Cooler isn't Top end performer but it is only about 3-4C behind DH14 on a OC'd processor...

It's pretty clear that something isn't seated right. 70C on Stock Clocks is just no...

My Old 860 was first Gen, bought it all when it came out, 5870 on release, jumped right onboard with 1156. I can accept that this chip may be a poor OC'r but I can't accept these temps.

So I'm going to reseat and see if I can find an improvement.

Update: Success! reseating has now worked, even tho it seemed to have a normal seating and a perfect even coat on the CPU It didn't want to work properly for some reason. Now I'm getting 46C max load under LinX, which is fantabulous. Doesn't change the fact I'm having issues OC'n but We'll see now that I can comfortably push it. Restart'n Time!

________

Oh and Quick question I'm not sure if this is new after this reseat of the heatsink but I just noticed (just installed my 6950's and updated bios recently also, so many things may have caused this), Out of my 10Gb RAM installed only says 6GB is usable. and says 4099MB is hardware reserved. I've had this issue once before can't remember how I fixed it I know I need memory remap within Bios Enabled haven't checked that yet.

Is the hardware reserved = to Memory on my Crossfire? That is what it seems to equal out too roughly would be 4096MB

35 min between being unhappy and having a max load tested?
No offense, but you should let w/e test your using, (hopefully prime blend of linx) for a few hours.
Good to see w/e temps you have are lower. Ive seen lots of case where the high temps were from stock cooling gel OR excess TIM on a aftermarket cooler. The stock cooler I'm using now(and have been for almost a year) has serious over TIM application .. and I fear replacing it...


--
hardware reserved can mean a number of things, but yes is usually related to the video memory. And in most cases you can limit or disable it(which is the best solution IMO for cards with 1gb+ of memory already)
