Help me getting my UCCC 10+ houres Prime Stable!!!

[Punisher!]

Very hard job man, because also a single relaxing change in the timings could result in a istant Prime crash or worse stability.

With these I can get them stable for about 4 houres and 30 min. @ 260Mhz and with 2,8V (in my MSI Neo2 Platinum) and it's the best result I managed to get:

Starting from these I will tell you the result of some changes I already tried:
- Drive strenght to weak OR TRRD to 2 will result in ERROR after few minutes!!!
- TRFC to 17 will result in ERROR after few SECS.!!!
- TRC to 12 will result in ERROR after 2 houres and 14 minutes.!
- with any voltage different from 2,8V (also 2,85V) I get error faster.


HELP! :D

My Corsair value 1gig UCCC sticks work best at low voltages, I can 250mhz dual channel at 2.5v on my DFI NF4 Ultra-D.

Hope this helps

I'd try lower volts, my friends UCCC hits 280 with 2.53v

Not on this motherboard for sure :D.

why dont you try

Dynamic Counter: Disabled
MAL: 8.0
ICL: 256
32byte: Enabled

I will, thanks man! :D

Nothing seems to work better than those I posted.

Hi Punisher!,
If the settings you have in your Sig are correct try dropping your HTT to X3 to keep HTT below 1000 and upping the voltage on your chip for stabillity. I found that to get the same overclock as I had with my 1GB Corsair 4400 TCCD I had to go from 1.44v to 1.52v on the chip as the memory controller needed more juice to stabilise it. My 3700+ is an early edition and wont reach your clocks but I have my GSkill 4000HZ running at 270x10 1:1 at 2.6v and the timings are 3.4.3.6 but 2.7v on your ram should be the max as it doesn't really respond well to high voltage.I also use the 180NFM(Rev.3)1T modded bios as it provides more stabillity for me than the newer bioses.As your A-Data are only rated at PC3200 could there be any kind of speed binning on the chips as mine are rated at PC4000?Do you have heat spreaders on? If not try a fan over them to see if it's a cooling issue as my ThermalRight XP-90 gives nice airflow over the ram. Good luck.

Thanks a lot for your advices man! I will do the tries you suggested (even if I already know HTT 3x doesn't help because I tried it and perhaps also CPU VDDQ because my CPU was rock stable at 270*11 syncronous with my old TCCDs at 1,45V).

Anyway I don't know what is wrong but a friend of mine with the same memories (A-Data UCCC I mean) on the same motherboard can get them easilly stable with latest bios at the timings I tried :(...

I noticed a strange thing:
- I can pass more houres of Prime95 near ~260 than near ~245 with the same timings. What could this depend from?

- Are you sure 1.8 NFM is the most stable bios for UCCC? Have you ever tried latest ones (also modded), what is the problem?

Hi Punisher,
The last bios I tried was the 1Ctccd Based on 1.C Beta3 bios and offered less stabillity than the one i'm using now so i never bothered with 1D.
Although your friend has the same make of memory and motherboard, unless it is your memory, motherboard, chip and power supply etc. You cannot assume that your setup will do the same. It's like me and my brother we both have identical rigs 3700+ CABGE 0515SPMW's,MSI Neo2 Plats etc, all apart from memory.When I brought the GSkill I gave him my corsair but he can't get the same overclock I did. Although on paper the rigs are identical they are worlds apart it's just the luck of the draw sometimes. Take my rig and yours both about the same on paper 3700+,MSI Neo2 Plats with Samsung UCCC but your performance outstrips mine easily, I cannot do 11X250 but can do 10X270 but yours can do 11X260 it could all be down to something like the memory controller on the chip which is slightly better. Have you tried using the 10X multi or even the 9X multi to see how stable you can get your memory and at what speed it loses stabillity?I would only use your friends results as a rough guide as to what to expect but not take them as a given that yours will do the same.
I hope you find a solution to your problem as I know how frustrating it can be at times but the overclock you have now is nothing to be dissappointed in.
Good luck.

Yeah man, it is really frustrating... have you read the second question?

Hi Punisher,
The 1.80 NFM is the most stable bios for me, as far as I know it was modded for TCCD and one has yet to be modded for UCCC. I have not tried 1.D bios as it's the same as 1.C Beta3 but with official support for FX60 as far as i'm aware.
If I were you I would drop my HTT to 3x and Multi to 8X or 9x and see where the memory starts throwing out errors. Then I would use a divder on the memory and see where the CPU tops out then just find a suitable compromise between the two which gives you the best performance.
If the settings in your sig are correct have you tried a little more voltage on the CPU to try and stabilise it?
Good luck.
