1090T Overclock - 1st Time Ever - Opinions Welcomed! :)

post #1 of 20
Thread Starter 
Hello all! Noob to the forums! I want to get your opinions on my OC...

All my specs should be in my sig...if you have any questions let me know!

I'm just wondering if my voltages, multiplier, etc... look safe? Also I have a few questions as well.

Detials on my OC:
After fooling around a bit, I think I got a stable system. I think I can push it more, but I want to run a prime95 at this last BIOS setting 1st. I ran 3DMark06 with no problems.

In my BIOS, I set the "CPU Voltage Control" +0.125 V. The setting then shows 1.575V. It also says that my "Normal CPU Vcore" is 1.45. When I boot up and do a CPU-Z, it shows ~1.392-1.408V. From my browsing the forums, I see that ~1.4V should be OK? Or do I have this voltage setting too high and shouldn't rely on CPU-Z for my voltage reading?

I changed the multiplier from x16 to x19 and that got me to ~3816.7MHz.

Through my testing, I found that I really wasn't cooling very well!! I even had an "uh-oh" moment! But I pulled the door off my case and now I'm much cooler (I think my case was holding in way too much hot air). I idle around 22°C. Running 3DMark06, my high is ~46°C. Are these temps OK? Is there a delta I need to add to my CoreTemp software offset? My cooling is Asetek 510LC Liquid Cooling System 120MM Radiator.

I have a Radeon 5870...I OC'ed that as well...tried to update to the AMD catalyst center (rev 11.06) and that didn't work. I went back to the "ATI" catalyst center rev 10.06 and then updated to 10.12 and am doing just fine. Anyone know why 11.06 doesn't work for me? Should I try 11.01-11.05?

Lastly, I'm trying to update my BIOS (I might ask this question in the mobo section) but I'm having issues...I have a Gigabyte 890GPA-UD3H rev 2.0 at BIOS rev FA....but I'm having issues updating! I tried using the @BIOS utility...I get a "need 64-bit" type error. I'll post a screen shot when I get one.

Again, all your comments are welcomed! Thanks in advance!

PS - In CPU-Z, it shows I have a 1095T?!? From browsing, I see that other people have had this issue...should I be worried? Also, I thought this was a 939 socket (and not a 938 like CPU-Z shows).

Feel free to read the numerous amounts of 1090T threads in OCN, so you can get a better idea what is normal and what may be bad. AMD CPUs can run up to 57-60C without running into much trouble and at >62C it should automatically shutdown (unless you have the x2 555/x4 B55, which can go up to 70C). Most people also reach 3.8ghz-4ghz with 1.4v.

According to this list: linky
Your motherboard has 4+1 phase VRMs, which can handle overclocking 4 core cpus, but can stuggle to support overclocking 6 cores. It will depend on if your VRMs are of good quality or not, as 4+1 phase VRMs and 6 cores with overclocking tend to stress the VRMs too much, causing them to fry or blow up. So I would see if other people with your board and CPU can clarify if it can handle overclocking x6's.

Wait for the 11.7 drivers coming up soon, though you can try 11.5 just to see if there are any performance differences from 10.12.

See pic attached...will the heat sink circled help with keeping the VRMs cool?

Also, if anyone can specifically answer my Vcore question 1st of what I have in the BIOS v what CPU-Z is reporting, that would be most appreciated. That is my biggest worry atm.

1095T is fine, CPU-Z reads it wrong sometimes. (My X4 turns into random codes, hehe )

As for voltage, it'll be fine as long as you raise the right thing in the BIOS and it reads around that in Windows. <- Those are nice temps, but check the temps with Prime)

I just did a little Prime95 test....peaked at 59°C. Not sure if I should go up from here. Maybe changing the HT clock to 210 might do me well?

Sounds like you're having normal early frustrations with our favorite CPU. It took me forever to find a real balance. Since your mobo and GPU's are different, I'll leave the specific advice about them to others - but I have found solace in a few freq's you might like to try:

1. FSB 230-240. Above that (while OC'ing anyway) and you'll get sick of the color blue.
2. If your ram can handle it: 9-9-9-24-31 CR1
3. Multiplier at 17-18. Use FSB to increase freq's. Yes, it's hotter, but I've never seen 50c even with my air cooled system. Stabilizing the 1090 above 18 is a real pain.
4. NB and HT at x11 above 220 FSB. Below that, x12. Don't touch the voltages!
5. Above 3.9 gHz, 1.45-1.5 VID is OK. The CPU will only use what it needs.
6. Screw 3D Mark 6. Use Mark 11. Your GPU is DX11!
7. AIDA64 is the best monitoring software around these days. It's not that expensive (considering what you've paid for your system), and it will tell you things about your system that the manufacturers cannot because most of our rigs are multi-manufactured!

Have fun, but be patient!

Update: on the 5870ATi front, I got 11.02 AMD Catalyst Center (and corresponding driver release) to instal and work correctly on my PC. I may try to go ahead and try 11.05, but I'm staying away from 11.06...plus I don't think I'll benefit that much. Issue closed.

I'm still looking for some feedback on my Vcore setting in my Bios versus Core Voltage reading in CPU-Z...

To jcfsusmc: thanks for the Mark11 remark...I used it last night...works well! Also, I was reading somewhere that I should look in CPU-Z under the SPD tab to see what my optimal memory timings should be? I'm at work atm but I think it said 9-9-9-25-33...I think I'll start playing with the memory after I start playing with the FSB (also, when you say FSB, you mean HT clock right or no?)

Can anyone comment why in my BIOS Vnormal is 1.4500V. I boost by +0.125V and it says in the BIOS Vcore is 1.575V, but when I read my Core Voltage in CPU-Z, it say ~1.408V. Should there be a drop? Should I be worried? Am I adjusting the correct voltage in the BIOS? Should I be adjusting the CPU NB VID Control Voltage instead? I have a Gigabyte 890GPA-UD3H rev 2.0 for my board... Any feedback is welcomed!

UPDATE!!!

The last thing that I did that has really helped me is that I updated my BIOS! WHHEEEWWW! I feel a lot better now. I only updated to version FF (instead of FGC). I was scared of their note --> Note: Remove boot PXE ROM & unlock CPU core function, please use previous BIOS version for full functionality.

My Vcore in BIOS normal/defaul settings is 1.275V now (was 1.450V)!!! That's what was worring me the most. When I pull up CPU-Z, the Core Voltage being reported is almost 1:1 (set for 1.425, CPU-Z=1.424)

I also have 1600 ram that I was running @ 1333 (not sure why)....so I boosted to manufacture's recommended settings to 1.65v and x8.00 mem setting to get to 1600.

Boosted NB to 1.200V
Boosted Vcore +0.15 --> 1.425V
Multiplier x19
Left bus speed @ 200
Left HT speed/multi alone

Now running @ 3800.0MHz and MUCH MORE COMFORTABLE!

See screen shots...

I'm going to do a little testing but I think I figured it out

Only think that I see that might be an issue is with GPU...I get some screen flicker on screen #2...not sure why...turned down the OC on GPU (even though it wasn't that much)

May try to go to the 4.0, but I think I'll have to play with the bus speed (probably 225 range I'm guessing)...may have to turn down the memory back to x6.66 multiplier too.

On to do some benchmarking...

Nice overclock man!. Im currently Stuck at 3.7ghz on My Amd965 c3. stock voltage and all because i need to get me a better PSU 500w won't cut it to go higher with my overclocking. click the link in my sig if you wanna see my 3.7 thanks And nice OC again keep trying if you got a decent pwrsupply/cooling i bet you could go further.
