Don't worry bro, I have a 16c difference between my coldest and hottest core which completely defies physics. Had this with multiple coolers, multiple reseats, multiple thermal pastes including Indigo Extreme and multiple application methods (for standard TIM, not the AS lol). It's just some core sensors are not as accurate as the others. Check it out, 16c difference at 4.8Ghz (and core 3 idled below ambient at one point LOL):


Also, my 2500k had a 12 degree difference between coldest and hottest (5Ghz OC @ 1.45v). Just ignore it. Personally unless the CPU I am using at the time has a terribly broken sensor like my core 3 and 6 on the 3930k, I average the cores and consider that my baseline temp. But if a core is DRASTICALLY lower or higher than the others, I check the thermal paste spread, if good I simply ignore that sensor completely.

[edit] Found a pic of my 2500k here it shows a 14c difference between coldest and hottest. The CPU is lapped perfectly also and this was after multiple reseats with IC7 thermal paste:

I'm really not sure, but it may have an effect. Could be another variable in the mix. I'm working on my 4.5Ghz oc now, just trying to keep a 0.3v difference between VCCSA and VCORE

ugotd8 mentioned he got better Cinebench scores when upping CPUPLL from 1.8 to 1.85v. Worth looking into perhaps, I'd start with that and see if your PPD changes for tomorrow, but let me know how it turns out please.

I'll do some tests and get some average scores of runs with the low voltages I have now and then with all of them raised. At least that will tell us if it makes a difference, then I can go from there, dropping one at a time to narrow down the culprit. But yeah I'll do it either tomorrow or Saturday and post the results here.

I don't ever get differences that extreme, but it's also something I try to avoid. The goal is to get the least differentiation between cores all else aside. The question about the Raystorm block is the point, and it does have an extreme bow that makes getting proper coverage across the whole spreader more difficult. You can see it in Martin's mounting tests.

Yeah I personally wouldn't buy raystorm again I can't recommend it. The pressure is uneven.

only thing I can afford.......though right now tongue.gif

edit: screw it. I'm going cut away some of the money I was saving for some other stuff and get the Koolance 370 instead

Where better to ask my question than on this forum. Is the RIVE or ASRock Extreme11 the better mobo. I have gotten a RIVE for my upcoming build but haven't opened it yet. I want max overclocks, plan on a quad 680 config, but am only using two hard drives one ssd and one hdd.

some people swear by AsRock; but I prefer Asus. Just cause my friend bought an AsRock mobo for Z68 (can't remember which one but one of the top end ones) and it has huge ripples causing his CPU voltage to constantly go all the way up to 1.4v+ and heating up fast under load.

He said he wouldn't buy AsRock again....but then again as I've said I'm biased. I've never used AsRock.

I'd ask in the general Intel motherboard forums if you've got time so you can ask Asus and Asrock owners for opinions.

There's zero gain from an ext 11 other than the sata controller and that is even a bit misleading. Check the top 30 heaven thread, then compare the cpus, and the cost of the two systems and have a lol or two.

I am having some trouble getting offset voltage working with the 125 strap. Does anyone have any pointers or is this something that doesn't work together? I can usually get to the windows logo loading screen, then it locks up. I feels like I am really close but I just need to change something in the BIOS.
