My 3.9GHz 1090T Guide

post #1 of 10
Thread Starter 
Hey all, first post here. I read quite a lot on here, but never post. I just spent about the last hour fine-tuning my settings for my PC. I have a rock-solid stable 3.9Ghz+2603NB+HT overclock. First I will list the important hardware that I have, then the Pictures/Guide, then my raw notes as I was overclocking, as well as some basic results taken with AIDA64 1.50.1241.

Enjoy!!!

PC Hardware/Software:
OS: Windows 7 x64 SP1 Updated 7/24/2011
CPU: AMD Phenom II X6 1090T
MOBO: Gigabyte GA-980FXA-UD5 v2 F6 BIOS
RAM: 8GB of DDR3. Running 4 sticks. Bought 2 Packs of Gskill F312800CL9D-4GBNQ.
CPU Heatsink: Noctura NH-D14 w/ Noctura Thermalpaste

Pictures/Guide:

As usual, i started out fresh, with just default settings, and i worked my way from there. The only settings I changed are on these pictures in attached.

I could run 3.6Ghz by just upping the multiplier, and ran fine, but I wanted more. I read several articles from different review sites, and even read a lot of results on here about it. But i could never really find an easy, exact guide. So I figured I would do a step by step. So after a little over an hour, these are the max, stable settings i could achieve. I'm pretty sure I am limited by my very, very cheap ram, but still, I am extremely pleased with this GSkill.

So at the end, this is what I ended up with:

CPU:3.2GHz<=>3.906GHz
MOBO:2.0GHz? NorthBridge+HT Link<=>2.604GHz (Cant remember default biggrin.gif)
RAM:1600MHz<=>1736MHz

In the following pictures, you can see I set my Clock to x18, my NB Freq. to x12, my CPU Freq. to 217, my HT Link to x12, my Memory Clock to x8. With the memory, I tried lower MHz with better timings, but it turned out the fastest result was with factory 9-9-9-24. The ONLY thing i changed on the ram (besides voltage) was the DCTs Mode to Ganged, and the Command Timing, which was 2T, but I changed it to 1T.

Voltage wise. The only Voltages I had to change was the DRAM volts, FROM 1.51V TO 1.57v, the NB Voltage TO 1.190v, the HT Link Voltage to 1.240v, and the CPU FROM 1.325v TO 1.4V.

The first two pictures is for the CPU/DRAM/Volts, and the third picture is for more advanced DRAM config. The ONLY reason I included the third picture, is because my motherboard wanted to run my ram at 11-11-11-29-2T. So in reality, all I done with the advanced DRAM settings, was set them to factory timings, besides the 1T Command timing.

(The only settings I changed on this screen is the 1T Command Timing. I set all the clocks to factory defaults)

***I forgot to Enable Ganging Mode on my RAM on this picture. So if you have 2 or 4 sticks of RAM, make sure its set to GANGED***

Like I said, here are my raw notes I took as I was overclocking. I will try to explain them as much as I can smile.gif You don't HAVE to read this, but it may be interesting to newer overclockers.

The format I used for taking my notes is this:

xxx =The GHz on the CPU, The MHz on the Northbridge and HT Link, The Command Timing, The RAM timings
xxxxx =The Memory Read benchmark inside of AIDA64 = This benchmark measures the maximum achiveable memory read bandwidth.
xxxxxxx =The Memory Write benchmark inside of AIDA64 = This benchmark measures the maximum achiveable memory write bandwidth.
xxxxxxxxx =The CPU Queen benchmark inside of AIDA64 = This benchmark measures the typical delay when the CPU reads data from system memory. Memory latency time means the penalty measured from the issuing of the read command until the data arrives to the integer registers of the CPU.
xxxxxxxxxxx =The FPU VP8 benchmark inside of AIDA64 = This benchmark measures video compression performance using the Google VP8 (WebM) video codec Version 0.9.5. FPU VP8 test encodes 1280x720 pixel ("HD ready") resolution video frames in 1-pass mode at 8192 kbps bitrate with best quality settings. The content of the frames are generated by the FPU Julia fractal module.

The *** Explanation*** for each of the notes is on the bottom. So read it as the settings and results first, then the explanation below (Explaining the settings and results above).

***Explanation: When I hit 3.8GHz on the CPU, I was pretty much finished OCing the CPU. From here, I decided to start upping the MHz on the Motherboard***

***Explanation: When I hit 1T on the RAM, I was pretty sure that was about it for OCing the RAM. This stuff is dirt cheap, so I didn't figure I would gain any speed. But I was wrong.***

3.8GHz + 2600MHzNB+HT 1T 8.8.8.23
read:10103
write:8753
queen:37016
vp8:3739

***Explanation: When I hit 1T, I started in on the Timings. I tried a ton of different combinations, but this was the only combo I could get stable. From here, I was going to start OCing the MHz on the ram.***

3.6GHz + 2543MHzNB+HT 1T 1700
read:10280
write:8514
queen:34948
vp8:3573

***Explanation: With this test, I was having a hard time keeping the timings that low. As you can see from the results when i lowered the timings, it was a very small gain. So i set the timings back to stock, and started working with the MHz on the RAM. To do this, i had to lower some multipliers to see where i could go with the RAM.***

3.8GHz + 2543MHzNB+HT 1T 1700
read:10387
write:8552
queen:36995
vp8:3755

***Explanation: With this test, once I knew the RAM was stable at 1700MHz, i started upping the clock to get my CPU back to 3.8GHz***

3.9GHz + 2603MHzNB+HT 1T 1735
read:10694
write:8754
queen:37856
vp8:3857

***Explanation: This was the finial test. Once I knew i could run 1700 on the ram, and 3.8GHz on the CPU, I really wanted my 2600MHz on the NorthBridge and HT Link. My motherboard wouldn't let me do x.x multiplier, so i was forced to raise the clock to get my NB and HT speed up, which required me to push the CPU and RAM just a little bit higher. After it booted and ran stable, i was finished**

So all in all, after all the overclocking, I managed to go from reading 8,530 Megabytes per second, to reading 10,694MBps. Thats a pretty big improvement with very cheap ram and non-watercooling. Overall, I'm pretty happy!

Thanks for giving this a read smile.gif If it helped, or you liked it, or have any questions, please post here and let me know!!!

Thanks!!!

Just for giggles, I just downloaded the free version of PCMark 7, and about to run it and attach results. My uptime on this OS install is a while. Installed on 2/5/2011 so the system is pretty dirty, and the SSD is like 80% full frown.gif In case it matters, I have multiple hard drives (just under 3TB in total), but my OS drive is an older OCZ Agility 2 50GB, and I have an old school HD4870 OCd to 790MHz Core and 1100MHz Memory, running the Catalyst 11.6 Drivers.


***Edit***

Just ran the basic PCMark 7 test. Scored 4054. Here is the result link: http://3dmark.com/pcm7/115289;jsessionid=1qtgfz0vaju5y?show_ads=true&page=%2Fpcm7%2F115289%3Fkey%3D6D2aKt24X35Qhme4BDexD7KWVBucHw

Actually both of them are on the CPU. CPU/NB is actually the IMC(Integrated Memory Controller). Also, don't run HT frequency at more than 2000mhz. It's most likely going to decrease performance and stability. Increasing its voltage is useless too, and probably dangerous.

Most overclockers raise the HT freq. And i got right at 1000MBps faster on the benchmark, as listed above.

No, they don't. Nobody does. It's common knowledge on this board that you don't raise the HT-link Frequency. That increase is because of the IMC overclock.

Normally 2600 ht shouldn't affect things because default htt 3.0 spec is rated 2.6ghz. Dunno why AMD lowered it to 2ghz. 2ghz/2.6ghz won't matter in games or applications. It should be the first thing to set back to original when things go wrong thou.

Now you should push your CPU-NB to 2800 or 3000 where the big gains are. Don't forget, ht stays <=2600 at all times.

For me there is a steep performance loss after 2100-2200. I don't think it will be any use of have it at more than 2000mhz unless you have like sli or tri sli 580s...

For me there is not. And someone made me pretty sure that you can't exceed 1000 ht on a single cpu system.

HT Link (Hypertransport bus/link) will degrade performance (due to signal degrading) beyond 2350Mhz - and there's no guarantee that yours will go that far without degrading. Having said that, there is nothing gained by overclocking the HT Link - it's merely a pipeline (albeit a pipeline used to carry data for just about everything on the board).
post #10 of 10
Yeah that's probably what AMD found out and recommend to board manufacturers. Because the advertised Htt 3.0 spec on AM2+ and AM3 boards is clearly 2600 mhz and there's even 3.1 spec which is 3200 mhz.
