5Ghz Wall?

Retell · Oct 1, 2011

Hey guys, I need a bit of help. I am currently working on a build for work.

Specs:

CPU LGA1155
Motherboard Asus Maximus IV Extreme-Z
Ram 16Gb DDR3 Kingston HyperX
SSD 1120 GB Kingston HyperX
SSD 2120 GB Kingston HyperX
PSU Corsair 1200w
Graphics 1 Evga GTX 580
Graphics 2 Evga GTX 580
Graphics 3 Evga GTX 580
CPU Waterblock EK-Supreme HF - Full Copper
Chipset Waterblock EK-FB ASUS Max4 Extreme - Acetal
GPU Waterblock 1 Heatkiller GPU-X³ GTX 570 / 580 -Hole Edition
GPU Waterblock 2 Heatkiller GPU-X³ GTX 570 / 580 -Hole Edition
GPU Waterblock 3 Heatkiller GPU-X³ GTX 570 / 580 -Hole Edition
Ram Waterblock x4 Koolance Ram-33
Radiator 1 Watercool HTF4 3x140
Radiator 2 Black Ice GT Xtreme 280
Reservoir FrozenQ Flex Tank
Pump Koolance PMP-450S
Fans x15 NZXT FX-140

I've got it up and running on a test bench. Overclocked to 5ghz and benched with LinX with zero problems (pic below). My problem is I cannot get any higher than 100mhz * 50. I've played with every setting except for skews (not experienced with that). Everytime I try to go just the slightest bit higher I get Debug Code 71 - PCH DXE SMM initialization is started. A few times I will also get 59 - CPU micro-code is not found or micro-code update is failed, but I am chalking that up to the fact that I am using a preproduction CPU. Is it possible that Intel may have left every voltage and multiplier unlocked but still block me from 5+ghz?

My chip is exactly the same way. I've also tried everything and from what I've found there are many people that hit a wall at a certain frequency and nothing can be done. Things like "internal voltage/wattage limiter" kicking in have been thrown around. I have no idea if it's true or not but it seems legitimate.

Damn_Smooth · Oct 1, 2011

I'm sorry man, but I think that is how Sandy Bridge is. I think it has a multiplier wall.

I don't own one so I'm definitely not speaking from experience, but I have read things that suggest that.

Edit: Damn it, ninja'd by erocker. Stupid phone.

How are people reaching 5.8ghz? I'm thinking about throwing a 2600k in on Monday.

Edit: Erocker are you using a production chip?

I think the people hitting that are very few and far between. They got extremely lucky and have a golden chip.

I'm not saying you are wrong, but it seems improbable to me that at least 200 people would have a high end water cooling setup and the perfect chip to break 5ghz.

sneekypeet · Oct 1, 2011

super pi 1M is not the test you want results from

You are speaking of stability in the OP not suicide benches

I have an ES 2600K and as far as I can tell there is no way for me to hit 4.6 stable, but my gigabyte Z68 does allow a 104.7mhz max with this chip. This is why so many people were binning CPU's!!!!

I assume you are tinkering with BIOS' if there is more than one? I assume the 0403 is the shipped bios?

I'm sorry man, I'm not trying to mislead you. I'm really not sure I know what I'm talking about. I've read a lot of things on the internet that turned out to be complete bullshit, this could easily be one of them.

Have you tried enabling the CPU PLL Overvoltage setting in your BIOS? It's been a while since I tried extreme OCing on my board, but I remember enabling this particular setting allowed me to OC up to a 52x multiplier.

Retell · Oct 1, 2011

@Peet we used Linx Simple Linpack to do a quick bench mark CPU load was 100% 5 minutes. Hardly a full burn-in I know. But it does mean that the OC isn't completely unstable. As far as tinkering with the BIOs, I have followed 5.5ghz guides (I'm no pro) and switched everything I felt comfortable with.

@Damn_Smooth, I fully understand. I'll give another chip a shot tomorrow. The more I think about it, the more I feel that Intel specifically did this to keep me from destroying their lil' guy.

4.6Ghz? That's very low for a 2600K, even when using low voltage. The problem with ES 2600K CPUs is, as far as I know, that they don't support PLL overvoltage, this is crucial for OCing beyond 5Ghz stable, but 4.6Ghz should be doable even without PLL overvoltage enabled...

Yessir. I can't even post 50* 100.4

Which revision is your CPU? D0 CPUs won't OC too much, D2 on the other hand...

EDIT: sorry, just noticed in your screenie your CPU is a D2, you just may have a CPU that won't OC too high; your core voltage is extremely high too! I could hit 5.2Ghz at 1.42V

Retell · Oct 1, 2011

D2, full specs of the chip are in the CPU-Z pic. Also that is just because I had core voltage set to auto at first.

15th Warlock · Oct 1, 2011

Let's see, I assume you disabled EIST, Turbo, all forms of over current and over temp protection, enabled Vcore load-line calibration?

Retell · Oct 1, 2011

To get to 5ghz I disabled speed step, turbo, and changed the Vcore LLC to 75%, when going for 5+ I set it to 100%. I have since tried disabling all other suspend modes, temp stuff, HT etc, as well as manual voltages.

Retell · Oct 4, 2011

Turned out to be the CPU, I stuck a 2600k in there and was able to boot 5.3ghz and can bench 5.1ghz. I believe I have CPU core at 1.575V. Does anyone have any more advice?

dumo · Oct 4, 2011

It seems like each SB "K" chip has specific Mhz limit which will trigger some kind of throttle if reached.

If for instance a 2600K can boot up to windows @ 52X multi then its Mhz limit will be any Mhz from 5200~5250 (with BCLK clocking up). If it can passed 5251Mhz then it probably will go to 5299Mhz which also able to boot up @ 53X multi....exept some chip has absolute limit @ 5299Mhz but can boot up with 53X @ 99.8 BCLK and not a Mhz higher...this is just for maximum bootable multi, stability will mostly depend on cooling.
