I am 24/7 stable on OCCT Small, OCCT Large, and OCCT 64-bit Linpack 90% Free Memory. I ran 4 passes of MemTest86+. There is a discrepancy between my memory/timings and QPI/NB speeds shown in the verification because my real RAM is being RMA'd as it was apart of that world-wide recall. So I am using my friends crappier RAM until I get my stuff back, I'll do another verification when I get my good RAM back!

CPU 210x21 = 4400MHz
RAM 210x8 = 1680MHz (7-7-7-20)
NB 210x19 = 3990MHz
QPI 210x18 = 3780MHz (7.56 GT/s)

Motherboard: X58 Classified
Batch#: 3849B041
**VCore: 1406mv
**VTT: 1400mv
**DRAM: 1530mv
Cooling: Water, (CPU + Chipset)

All other voltages at Stock. The DRAM is at stock but my mobo puts it about 30mv higher than it's setting of "1.5v". Both my VTT and VCore are set to 1.4, however the VCore measures 1.406 under load. The BIOS reports my VTT being 1.49v, which is a lot higher than it really is.

**(measured with mutli-meter under full load 0.5% +/- accuracy)

My temps are 72c during Linpack, and 65c during OCCT. My VREG's are pretty cool and stay around 50-55c depending on load. I live in an non-air conditioned dorm room with higher than normal ambient temps in the summer.
Man I wish I had your temps, do you have HT on? I have a dual and triple rad and my temps are sky high, waters really warm so the cpu is just pushing out a TON of heat.

If i could control the heat a bit better I could probably hit 4.7 stable. I can get it to boot but I get bluescreens if I do anything cpu intensive. PCIE Freq at 102 allows bclk over 220

anyone with a gigabyte ud4p or ud5 want to rock and share with me your BIOS settings, I have the d0 chip, and am currently at 3.8 but want to go a tad higher, and not sure how to do it

Anyone experienced a weird behaviour of default vCore - like it changed to much higher number? In BIOS it before displayed 1.25V, now it says 1.30V. I cant get to overclocks i could before ran stable, now it wont even post.

HT Off! I tried briefly to get HT stable at 4.2GHz but it seemed no matter the voltage it just didn't want to go. My board wont boot over 221MHz, but it looks like it can't get stable over 215 or so. I will try the PCI-E trick, do you think that will work? Everyone else with a Classified is getting 230+ bclk, and I am stuck at sub 215.

I am pretty sure my water temp is "room temp" before it goes back into the CPU block, because if I use my fingers to stop 1 of my 3 fans on my radiator, my temps don't go up at all. So basically just 2 fans on my Radiator is all I need apparently lol. When I mounted my block, I did a Kuntz Certified mount, which means using LOTS of paste, paste everywhere, like half a tube of paste, and then using maximum pressure to bolt it down. My 4 bolts are as tight as my hands/fingers can turn them, far beyond what most people would dare do I bet. I tightened each one a full turn, in a clockwise pattern, until they were all fully tight. When you do a full-paste mount, it'll take a few weeks of use/thermal cycling to get your temps down.

half a tube of thermal paste? I used just a tiny bit after lapping the block and the cpu. Ive never heard of that method, will have to try it sometime!

Have you tried upping your vcore for 220? Mine needed a bump from 4400 to 4620 and needs another huge jump to 1.5ish for the last 80 mhz for 4.7.

if you want to test the pcie trick turn down the multi and boot it at 220. If its stable up the pcie to 103 and try booting at 221, if it fails try 106. You should be able to boot above 221 with some extra pcie frequency. I heard classifieds are finnicky though but dont give up!

My board wont boot at anything past 102 pcie without a hard mod of the mobo but it was enough to get me to 225, at 226 wont boot but Im not sure if its the mobo or cpu since its not stable at all @ 4.7 1.5 vcore. Im already at 1.34 uncore and would like to keep in spec so I have not tried raising it more.

Alright, I have tried EVERYTHING to get this thing to boot past 220. I can actually do 221 fine, always could, it was 222+ where it stops booting. I've done insane voltages, 104 PCI-E, various weird settings, spread spectrum, 1.8v DRAM, it just really doesn't want to go that high. It doesn't matter, the board isn't stale at 215. I can boot and do everything fine, but it wont pass Linpack or OCCT at 215....even 215x18 or something. 212 is the highest it's stable, which is 4.45GHz, which is nice. It just kinda sucks I get the ONE Classified that has a bunk bclk lol. And I spent $525 on this board!

anything north of 220 is hard on any board. My $200 Asus P6T (vanilla base model) will do 220 BLCK with a bit of mucking about.

that was one of the reasons I steered clear of the rampage extreme II and the EVGA classified; I felt the additional cost did not demonstrate scaled performance improvement.
