post #12611 of 13131
Crosshaır IV Formula and Crosshaır IV Extreme have a different size VRM/NB cooling system. I no have a low profile RAM, but i know how install second fan with normal profile ram. I have 4 slots samsung DH0-CH9 4x4gb. Crosshair IV Extreme VRM/NB cooling system have a identical height on cpu level with my ram, its about 28-30mm on both sides.

God i love this motherboard.. I want a formula Z now lol, but am going to wait for the 1000 series.. smile.gif

Oh temps, well using a h100i push pull in a ~28-30c room i get into the mid 60's with hwmonitor, and the temps came down after using IC Diamond 24 tim

Hello, Excuse me for my English is bad, but here's my problem: I have a FX -8350 on my Crosshair IV Formula BIOS 3027, everything works except when I want to run OCCT , then the FSB up and down, including the frequency of the processor. And overclocked to 4.5 GHz , it can rise to more than 5.7 GHz and 3.0 GHz down. The memory used 4 x 2GB Kingston 1600MHz. Before I had a 1090T and no problems. Do you have any idea? In advance, thank you wink.gif

Be sure to disable all power saving features. Sounds like you may have Turbo Core enabled too. There are a few links to help you here

Hay everyone,
I have been following this forum for a wile now and love it. I just swapped out my PII 1090t (OCed to 4.1 G-1.5v daily use) for an FX-8320. After reading everything on here I took a chance that it would work, and it does, very well. I am running stable for 3 days now at 4.4GHZ (1.47v) idle tmeps 29c CPU and 19c all cores.
COOLING-
After 6 hours of prime 95 44-45c CPU 39-41c all CORES.
Koolance still has the full MoBo water block for the CH IV Ex. http://koolance.com/index.php?route=product/category&path=38_77 ($124) with that block on my NB temps never hit above 35c, with the stock cooler, temps always at least mid 40s and near 60c under load/stress test, a worth while addition.

Thank you for the answer, but I did all the tests with and without Turbo Core, with and without energy efficiency. In fact, the FSB , even in normal operation at 4GHz can vary from 175MHz to 250MHz more ! It does me has ever done with the 1090T. Could this be a compatibility problem between the FX -8350 and memory?

Here is an example of overclocking to 4.4GHz with totes features power saving disabled. The memory frequency is set manually on 1600MHz instead of Auto.

Sorry, I just answered in the previous post smile.gif
The phenomenon occurs only when the CPU is under full load on all cores , such as OCCT or Prime95. I've tried everything, the original frequencies , overclocked , with or without energy saving options , auto or manual settings , except for the memory where I put either auto or manually 1600MHz. For cons , I left the memory settings ( CAS and other cases ) by auto.

No answer? I think that somebody must have an idea ... confused.gif

It's one of the reasons I am hesitant to plonk the funds down on the new CPUs' and sticking with 1100T. That and being away from my system. At least I'll have a new 1100T waiting for me when I finally make it back. AMD honored my RMA and shipped the new one back. Should be there sometime this week. thumb.gif

Well anyway, unless AMD tweeked the IMC on the die, I would not expect to run faster than 1600 series RAM. Of course you could always plonk the funds down for 2000(Max capable RAM for the Crosshair IV) series, but I wouldn't because the newer Enthusiast Boards are capable of so much more. Throwing money into 2000 would be like throwing money into 1333 RAM unless of course you're on your final desktop platform. biggrin.gif
This. Is the system 24/7 stable @ Load? mellowsmiley.gif

Happy New Year All. yessir.gif

Would it also be a problem with my memory to the fluctuations of the FSB?
post #12620 of 13131
I think I found the solution, in fact it seems to me that this is a bug with OCCT. I was using version 4.3.2, and since tonight, version 4.4.0 which is more stable, I have more than a few drops of frequencies, and the FSB varies more than one MHz. This is much more normal!
