i7 2600k w/ maximus iv extreme - multiplier problem

[max11b]

Hi, I recently finished my build and went straight into OCing to 4.8 per a guide on this forum by you and after I follow the guide to the end, I reboot and went into windows itself. To confirm the OC, I used the ROG - CPUID and saw that the processor is still running at stock 3.4ghz. Another thing, hyper-threading is enabled but CPUID shows 4 instead of 8 threads. here's the link that I used and I followed the quick OC guide

My setup as follows

i7 2600k
Maximus IV extreme B3 revision / Bios 1303
Matrix Platinum gtx 580 OC to 925ghz / 1.150v
Corsair XMS 3 4x4gb 1600C9
H70 cooler

Thanks, Max

Hi Max,

Clear CMOS, check CPUID at stock to see if HT is enabled. Also ensure you are using the latest version of CPU-Z.

I cleared CMOS, thread shows 4, core shows 2, and I'm using the regular CPU-Z 1.58 not the ASUS ROG version. Do I need to do something in the BIOS? Apologies in advance I'm new to ASUS mb, evga mb was what I had last.

Could it be that I'm using windows 7 home premium 64bit sp1. Also, my mb bios is ver.1303

Flash to the latest BIOS (1850 it is listed in this forum), let me know what that does. If that does not help, save a screenshot of the CPU configuration screen of EFI to a flash drive and upload it here please.

This is a retail CPU and not an ES right?

Also, on the mb I noticed that the power plug for the mb is a 4-pin instead of 8-pin. Any significant difference?

yes, retail I bought it through tigerdirect "Intel Core i7-2600K BX80623I72600K Unlocked Processor - Quad Core, 8MB L3 Cache, 3.40 GHz, Socket H2 (LGA1155), Retail" . what's ES? and do you have a guide on how to reflash the bios, I planned on reflashing the second bios

FYI, when I setup the new rig I took the ssd from my last rig and stuck it into the new rig. does it matter if a fresh OS install happen or not?

That's the problem I bet - reinstall the OS.

i would still flash to the newer bios. there is a bios utility that uploads the bios file or you can use USB Bios flashback which is quicker. tips here: http://www.asusrog.com/forums/showth...bios+flashback

for your power connector, the board support 8 pin power. there may be a cap covering the other 4 pins so be sure to take it off. and if your power supply supports 8pin which most these days should you should definitely use it.
