Bulldozer meets ADATA XPG - DDR3 frequency world record!
Hey guys! I was experimenting with Bulldozer over the last few days and was very surprised, that it's not only great for high cpu frequency but also for veryhigh memory overclocks! So I decided to take my latest and greatest ADATA modules out for a spin to get some scores with AMD.

Bench system:
- ADATA XPG - Gaming Series 2.0 - 2400 MHz, CL10-11-10-30
- AMD FX-8150 (8 Cores, 3,6 GHz)
- ASUS Crosshair V (990FX)
- ADATA SSD S511, 60 GB
- Enermax Revolution 85+ (920 Watt)
Well, first I was going for about 2800 MHz with just one module and was pretty difficult to stabilize. But the more time I spent with the system, the better it worked out and I couldn't believe my eyes when i passed the 3000 MHz just for validation ... I mean, on AMD ... who would have thought?! :cool:
So I decided to go on and ended up with a validation of 3200 MHz:

So welcome ADATA and AMD to 3000 MHz club! :toast:

I guess Bulldozer is now in for the race to grab the memory frequency record. It should be not too hard, because this was the first bulldozer I tried. With a little binning and a bit of luck the 3300 Mhz are possible imo! :shrug:
Surprising as this already is, I figured out that the right voltages (not too high, Bulldozer no likey!) and a high (yeah, not too high) ht frequency at bootup can be pretty stable for benchmarks too. As motivated as I was, I plugged in another xpg module and upped the cores to 7 GHz - still no problem for our little Bulldozer! :up:
As a screenshot would not do justice, I recorded a little video. It's made out of to runs cut into one, because during the successful one it was impossible to read anything on the cpu-z tab. So here it is: a bootup at 7,2 GHz with 2880 CL10-13-10-31 2T and a SuperPI 1M run at incredible 7,5 GHz/3000 MHz! I also tried to give a quick insight into the currently applied bios settings.

Regarding the memory modules, they are built with Hynix chips and only single sided (for building 4 gb modules with the same series). ADATA sent me a retail package, so no special binning involved. I removed the heatspreader for you to have a better look:

For the German speaking guys there is a thread on overclockers.at: http://www.overclockers.at/benchmark...-ddr3-w_227175

Update, 9.11.2011

After an awful night of sleep I decided to try out a second bulldozer chip (reaches just 8 ghz on one core, no MHz more ...). It booted up with the exact same settings but scaled way better to cold and voltage. So after 30 minutes of playing around at very high voltages - 1,725 Volt on NB/CPU and nearly 2 volts on the memory - I went over the 3300 MHz barrier and validated the result:

Well, AMD takes the crown of cpu and memory frequency. :toast:

Thanks to ADATA, AMD and ASUS!

that chv is pretty darn good...

goood rams too

nice work mat!

Dayum... Nice.

Wasn't expecting Hynix modules :)

How far can you go on the lower straps? 3:14 or whatever it is.

No difference at all iirc. HT stops at 290 something (without much testing), but I went with lower bus speed and higher multi instead.

Awesome!

What can that ram do with tighter timings like 7-9-7 or something?

I did not try. I wanted to go for performance and tweaking and ended up with suicide runs ... again!

those are hynix bro, they can't do tight subtimings lol

I had the adata hynix one-sided, and they can't be tightened

Great work mat :up: 3200 is AWESOME!

Hynix are great for RAM validations. My HyperX H2O Hynix do 2600MHz 13-14-13-31 @ 1.68V on A6-3650 :D That high latency isn't needed of course, I was just testing. Should be possible with 11-14-13-31 as well.

wow, congratulations! Very nice. And RAM was not under LN2, great result!

Very good job :up:

Did you try different slots?
And did you try to find max CPU-NB clock with RAM on lower multi?

Thanks!

Yes, the right slot is very important. I tried every slot and only the red ones seem to work that good on the Crosshair V. The inner red slot worked the best!

At first I thought I was NB Frequency bound at 27xx MHz, so I experimented a bit and got up to 3100 MHz without any troubles - well using ln2 and a high nb/cpu voltage. ;)

Awesome! I actually I was looking at the 2000mhz kit on newegg.com I wonder if they use the same modules..
