Hi guys,

Today i purchased the Gigabyte GA 890FXA-UD7 and paired it with my 1090T.
Out of the box the mobo was running BIOS ver F1.
After setting up and reinstalling the OS, tried to OC the proccy but to my amazement i wasnt able to hit 4GHz :O. It didnt matter how much vcore i fed but the mobo just wudnt oc the proccy. It wud fail to POST the 1st time & then reboot & show that OC failed.
Downloaded & flashed the latest BIOS ver F2.
Still the same issues.

I mean this very same proccy used to do 4.3Ghz on my 890GXM-G65, which costs less than half of wat the UD7 costs and its supposed be a great OC'r.

Other hardware used :
CPU Cooler > CM Hyper N620
Ram > GSkill 2*1 GB 1600MHz CL9
PSU > Corsair TX850
GPU > 2*8800GTS 320MB (will try removing 1 of these)

These were the very same hardware that I was using with the 890GXM-G65.
Also i had disabled AMD C&Q, C1E, AMD Virtualisation, & Core Performance Boost.

Please help me OC this thing. This is the 1st time i've failed to OC a setup. :(
 
This can very much happen. Not that you will never hit 4 Ghz, just that it is a totally different board. I do not have much knowledge about AMD OC, but can suggest the following basics.

1. Initially try the OC, by leaving the RAM to default. Just tweak the voltage to EPP and leave it at 1 : 1.

2. Try non-SLI.

3. There have to be other settings which you are missing out (other voltage settings, like my board has SBvoltage. DDREF_v, NB Voltage) which also would need to be strengthened. You are missing something critical which is being overshadowed by 'too much vCore'.

To correlate:

Currently I am facing a similar issue. My E7400 used to hit 4.00 Ghz, smooth as butter. Now my Q9550 [e0] just refuses to go beyond 3.6 Ghz no matter how much vCore I lay at its feet. I went till 1.45v even, still failed. And the rest of the world hits 4.0 Ghz at 1.2-1.35v. So obviously I am too missing something.

Also try by keeping you power option on High Performance.
 
^^^ bro ur situation is a bit diff than mine. U've change ur proccy from a dual to a quad.
but out here i've only chnaged the mobo and that too to a better one.
 
Please tell how you are trying to overclock ? through HTT or through Multiplier ? What settings you have used till date in both the Mb's,.
 
Bit OT, but how much did u pay for the mobo and what case are u using.

Anyway as far as OC is concerned, first would suggest u update to the latest bios. most of the 890 series boards were out in a hurry and most of them dont have great first bios's. So first update the bios. Secondly, it looks like ure using the nvidia hack to get sli running. That could be a potential issue as well.

I know that. What I advised was purely generic. You have undergone a major hardware change. It does not just that easily translate that you get a better motherboard, so it will OC without hassle out of the box. Sorry if you found my post pointless. Was just pointing out you could be missing some critical factor, since you yourself mentioned even high vCore is not doing the job.
 
@darkstar -> Settings on the MSI 890GXM-G65 - 200*20.5 = 4.1GHz @ 1.425v (24/7), Ram @ 1600MHZ ,7-8-7-20,
-> 1st tried the same settings on the new mobo but no gud. Tried both multi & htt but no luck. Even updated BIOS to F2 (latest) same result.
-> Will try putting the sticks on the White slots instead of the Blue ones.

@mav2000 -> Paid 15k for the mobo. Case is a CM 690. The mobo being a XL-ATX, i had to adjust the PSU a bit (read unscrewed from the chassis and is lying at the bottom of the chassis ;) )
-> Have updated BIOS to the latest F2 version but same issue.
-> SLI hack cannot be the culprit cuz that thing only kicks in when windows starts to boot. Moreover i've already done a clean install of the OS, so the hack is no more.
 
The price of the board doesnt matter, and though I am not familiar with both after and before boards but in simple words, UD7 would have lots of options in the BIOS, though it might be initially a bit hard to get an overclock, but once you understand the options in the BIOS by reading manual/reviews and general overclocking guide, you would/should be able to achieve higher clocks on it.
 
What I am suggesting may sound noobish but it has helped me some time earlier, bot into windows normally by whatever settings you can and then use AMD Overdrive to change the settings whilst in windows.

then report.
 
^^ But he has tried the OC by increasing the multi too, and if that is also not working then the ram doesn't seem like the culprit.

Ripjaws does not play well with giga sometimes...so that could be an issue as well.

Yep that seems to be a prob. cant run tighter timings than CL9 at 1600MHz
BTW the oc prob is resolved. Just reset the bios by removing the BIOS battery and now i can OC.
 
did you not down NB and HT voltages while on previous boards?

3.8-3.9GHz is fine on all boards

3.9GHz and above is the place where the Vtt-NB and HT voltages do come into play much.

if possible to use older board, check those voltages and note them down.
 
Now doiing 4.1GHz proccy, 3.1GHz NB & 2.6GHz HTT
NB & HTT freqs r a lot better than wat my prev mobo cud do.
My only grudge is the ram timings. Rev mobo did 7-8-7-20 at 1600MHz but this biatch doesnt boot at anything lower than CL9 at 1600MHz no matter how much i feed it.
 
Older RAMs are an issue sometimes on newer boards. I have experienced same issues (not on same board though).

Also Ripjaws mostly were for P55 platform so that's another problem on AMD platform.
