Anyone else with this problem? I really don't want to reflash bios which fixed the issue until it showed up again

Never heard of this. Make sure you have the latest bios and reflash. You know you have a backup so don't be scared. I have flashed over 1000 bios chips without bricking one. Sounds like when you went for a higher overclock and when you rebooted it reset to defaults to post. Iv'e seen this before but never cpuz display incorrect values. Download speccy instead and compare results.

Does anyone know if using the on board Twin-Power Cooling (On board water cooling) Is worth it?

I'm about to do a custom loop and if i add this in, because the barbs are so much smaller it might create and choke point yes?
The tubes i'm going to use for CPU block will be 7/16" ID 5/8 OD. I would also use something like this to make it possible to connect to the barbs on the board.

Don't know if this will negatively effect temps/pump efficiency...

Thoughts?

I tied mine into the CPU only loop at the temps are still great. I used 1/2" tubing into the inlet of my CPU block and 3"8" from the outlet to the Mosfet block. The outlet of the mosfet block 3/8" back up to the Res, where 1/2" resumes again.

I could have made the whole loop 3/8" but I already had the tubing and monsoon fittings so I have a loop size reduced at the CPU block outlet. I wouldn't mess with the reducer fitting you posted above if I were you.

Will the 3/8" tube fit correctly on the pump/CPU block? I thought that size would be to small to fit?

let me explain it a bit better. My loop looks like this.

the inlet on my CPU block has a 1/2" barb.

The outlet on my CPU block has a 3/8" barb.

My loop goes from the outlet of the CPU to the bottom Mosfet barb.

From the top mosfet barb the loop runs up to my res which has a 3/8" inlet

from the res 1/2" outlet to my pump 1/2" inlet.

I can upload some pics here this week.

basically I have a loop that reduces at the CPU block and increases at the Res.

May I ask why? This reducer looks like something that meets industry standards and can survive pressures which are impossible in WC.

Hi,

Just completed building a machine (minus ssd/hdd at this stage - using a temp gpu in place).

I seem to have an issue with Dual Channel mode, that Im currently trouble shooting. I have bought 16GB (2x8GB) of Gskill trident 2133 RAM 9-11-11-31 timings 1.6v

initially I had the ram in A2/B2, set at the correct speed/timings and ran memtest and received 9 errors during test #7. I moved the ram to A1/B1 and the machine powered off/on 3 times before going to the BIOS and the speeds/timings wouldnt stick.

I have just finished testing each stick individually in slot A1, no errors.

Im about to update to the latest BIOS on the ASrock site. 2.0 as it mentions memory compatibility. Any ideas are welcome.

still fails to boot with dimms in A1/B1 after loading xmp profile.

running memtest again in A2/B2 after BIOS update.

Any ideas to whether its the board or RAM at fault here? or is this by design? I wouldnt think so seeing as it will boot with 1 stick at the correct speeds in A1.

EDIT: got errors straight away in with both sticks.. testing downclocked to 1600 now.

so 1600 works fine, no errors from memtest.

I set the DRAM freq to DDR3-2000 (1:10) and it passed fine, no errors. However I did notice something strange and that memtest reported the memory as 2666 instead of 2000. using 10-14-14-36.

Im off to bed now, maybe someone can shed some light on this wierdness for me while I sleep.

Thanks.

found an old hdd laying about, used it to install windows.

prime95 didnt like the 2000 ram for some reason. one worker always stopped after 6 tests or so on blend.

I havent even overclocked the cpu yet... 1866 seems to be fine with prime, what am I missing?
