Preview - Asrock 990FX Fatal1ty 990FX Professional - Page 29

Some CPUs will run 16GB. and some won't. There are no guarantees once you go beyond what AMD officially supports. In many cases slowing the timings down helps as does upping the RAM, CPU-NB and HT voltages.

Most anyone can run quality 2x 4GB. RAM @ 2133 MHz. (if the RAM is capable), on a decent mobo with a Vishera CPU. Asrock like all mobo makers regularly updates their BIOS to fix RAM compatibility issues. V1.93 is reported to do this but we have no details at this time and it was pulled down when it was found to corrupt some systems. Hopefully they fixed whatever the BIOS issue was.

So did you test that beta 1.93 already? If yes, how do you see it...I believe I do have some RAM compatibility issues...as yesterday new setting worked, but this morning my machine refuse to boot up!

No I haven't tested V1.93 yet. They pulled it before I had a chance to download and try due to it causing corruption on some systems. I have been trying to get an answer from Asrock as to if V1.93 has been repaired and exactly what changes it makes compared to V1.91A/B. So far no reply so I don't know what the deal is.

As far as boot issues this may be a timing issue on cold boot. You may be able to slow the timings a bit to eliminate the cold boot issue. The BIOS only allows so much time to read and try to boot using the user set RAM parameters. If it fails the user set parameters, it goes to the SPD default settings and if that fails it tries a lookup table based on the RAM ID. If that fails it doesn't boot. Usually after a couple cold boot attempts the RAM will be warmed up enough and the tight RAM timings will work and the system will boot.

Alright...but how about that 1.91B...as I have only 1.91A version from Asrock site on my machine...I can see that this mobo has potential, but it needs better BIOS...something Asus like did on their mobo's....
I would like to ask you if there's any improvement stability wise with 1.91B and where to get it from?

that's a great point, everything seems to be in place. its very effective at overclocking but the LLC features need working on.
post #286 of 416
LLC as much as I can see isn't as bad as some other mobo's...certainly is better than GB 990FX series, even any of MSI's but worse than Asus. I mean, using 25% is as stable as it gets, voltage wise, but this is still far cry from Saber for an example.
However, features and look alone is killing Asus, especially for the price I paid for it...lool...which equals to close 0...swap this and that and I am even on financial gain...lool!
Besides all, I would like to keep it as I found that VM's and Adobe works nice still can't enable that bloody OpenCL in anything despite I am using latest drivers all patches and every possible tweak you could imagine...no OpenCL for me...full stop.
Which is rather stupid...for some reason Adobe claimed they worked in close relation to the AMD...but obviously this works not...
I would like to find out if that 1.91B or 1.93 BIOS does the miracles to my setup...chasing around the net I've found that RAM is kinda AH...so, we'll see the results pretty soon I believe! Asrock still haven't answered my cries...

I don't know that V1.91B will cure your RAM issues. All that I know it corrects is the 2133 MHz. RAM frequency selection option in BIOS, which did not function properly on V1.90. You can obtain beta V1.91B from Asrock by asking.

If you haven't tried working the CPU-NB and HT voltages completely, you should. You can also contact Asrock Tech Support with your hardware details and perhaps they can advise on both the RAM and OpenCL ?

guys I have a major issue,

http://www.overclock.net/t/1395102/problem-that-needs-solving-firestrike-combined-test


im planning on getting some ram on the weekend, im thinking on tridentsx 2400mhz 2*4gb or what else is a good option? btw if these sticks are overkill, I like overkill.

im trying to eliminate all possibilities with my mentioned problem.

any help would be good, thanks
post #289 of 416
I highly doubt the RAM frequency is the issue. Did you notice that the test you were comparing against used 4x 2GB. DIMMs? That may have a significant impact on RAM performance with all DIMM slots occupied depending on how the benchmark uses the available RAM.

Are your scores in other benches typical or real low? If the only bench where you have issues is Firestrike then I'd expect a GPU driver issue or physics conflict of some sort, if everything is configured properly. I read that you've tried many things to resolve the issue.

I don't have any experience with Firestrike. I have found 3DMark very inconsistent from test to test with no changes to the system and fresh boots between tests.

its only firestrike combined.

people advised me on ram, fsb/cpunb/stability etc etc but none of that changed the problem

futuremark said it might be drivers, I tried all the ones that were compatible, apart from new ones.

im at a loss and don't have a clue.

and I tried all sorts of ram configs, from single dim to 4 dimms
