Yeah but who said you cant damage an IMC from to much DIMM voltage?

I just RMA'd a P45 with a bad MC, these cpu's have the IMC on them so your board wont go bad with i5/i7, your cpu will.

So FYI - Overvolting your ram will cause issues to your cpu....

an extra 100 - 200MHz on your ram OC doesnt do squat aside from maybe a benchmarks score... So if your a bencher, just change it back...

All this DDR3 is rated at 1.65 and below for a reason...

Now to the issue I am having.....
Prime95 stopped responding, but computer stays on. No BSOD, No error or failed worker....

Any Ideas??

Edit: I was trying for 190 x 21 or 200 x 20 for 4.0, it wasnt working out, even cranking voltage so it was getting 1.36 core and 1.34 VTT....

Dropped down to 180 x 21 - 3.76 - 1.32 core 1.30 vtt (all windows load voltages) left OCCT running and went to work.. fingers crossed

I think you might still be missing the point. Poisoner's issue isn't something new. This is something that has been ongoing and was discussed earlier in the thread. IT IS HIGHLY RECOMENDED TO KEEEP DRAM/DIMM VOLTAGE AND VTT/IMC/QPI/UNCORE VOLTAGE WITHIN .5V OF EACH OTHER. . Now go look at his screen shot and loot at his stock CPU VTT. So what happens when he runs stock or near stock vtt with 1.65v RAM ? From what I've read it is one of the easiest ways to trash a CPU.

What sizzle said. I did mine on accident. Didn't under volt the ram from its stock 1.65 when I put my cpu at stock.

hey there. i use my pc for primarily gaming and web surfing. first time i5 overclocker here. followed dembo1305 BIOS guide listed on this club and got my chip to 3.8ghz at 1.21 vcore on the bios!!!

CPU Z Validation: http://valid.canardpc.com/show_oc.php?id=1545433

idle temps: 38c
load temps: max on linpack 80c
passed 6 hours of prime

passed 1 hour of occt linpack test on max mode. min/max temps and all details shown in attachment thanks alot dembo1305!!!!!!!

And that sucks for you but hopefully the rest of us can learn a little something from your costly mistake.

In some guides the .5v window is one of the first things listed. Other than that it doesn't get much press. Probably because with most overclocked systems going over that .5v difference is rather hard to achieve. Then you have these 760's that are capable of running very low VTT with some decent overclock numbers. Add that at one time Intel recomended not going over 1.2v on the VTT and you still get people giving "just don't go over 1.2v VTT" advice. Of course at that time Intel recomended 1.35v RAM for i5's too so that wouldn't be an issue if you have low voltage RAM. Since then numbers have been revised and running higher VTT and 1.65v RAM is common but you still have a lot of people leary of high VTT numbers when really we should be more concerned with low VTT numbers if we are running 1.65v RAM IMO.

Sounds bad.. If I would have known that, or been able to understand what you were getting at, I would have said thanks for the heads up. Not write an offensive post..

So your saying that we shouldnt go higher than 1.2 VTT, or we should be higher than 1.2 VTT? I'm using the 1.35v RAM..

LOL, NO I'm not saying that at all. I'm saying that the people who keep saying "just stay below 1.2v VTT" might be giving bad advice in some cases.

Keep VTT and RAM Voltage within .5v of each other. With your 1.35v RAM it won't be an issue.

Freeze, Most likely something on the uncore side. Normally I'd say bump the VTT if you were already at 1.34VTT that most likely won't do you much good. IDK List your settings and maybe someone will take a crack at it.

Please keep in mind I'm one of the people here that have read all 62'pages
About 15 pages into this thread it was about the .5v recommendation
Now I see it pop up again in conversation

But that's not possible if you have 1.65 v ram
If you run 1.6v on the vtt your going to kill it
I don't see how safely that works
And that's within the .5v
So please explain this to me
There's no explanation some 62 threads now


There's an explanation for 1.3v plus not going over 1.25 or whatever but not 1.65

It seems Ludacris to think the vtt must be that high other life expectancy is 50% less

In this situation you seem to be getting .5 and .05 confused. They are saying to keep the IMC and RAM voltage within .5v of each other. So for 1.65v RAM you need and IMC voltage of at least 1.15v. For the people with 1.35v ram this isn't really a problem.
