The temp and HT link frequency is what's holding your OC down.

Temp under load is the same for my main system, it settles at around 59c-61c. PWM fan take I little while to catch-up. Temperature is going to come down, and improve.

I read somewhere HT can go as high as 2000MHz, Let's see if that is true. I have seen HT over 1300MHz, but I can't remember where. ..My main computer HT operates the same as in (lower speed photo), Ultra stable.

Ram has been drop to 166MHz bus in the BIOS, it can't handle that kind of speed when set to 200MHz in the BIOS, but my main computer memory "4GB" in my main computer can.

I know where the problems are, but it's difficult to fix & a lot of work. I also had to enable the Southbridge fan during this test, normally this is off.

NEW UPDATES:

Three new updates were added yesterday.

Modified "cooler bracket holder" was tested for the first time, VRM Temp did improve.

Northbridge cooler was changed from Noctua to a direct touch heatpipe cooler.

CPU fan had changed from Zalman CNPS8900 (Hacked) back to modified CNPS8700.


THE MOTHERBOARD

Motherboard has new VRM & new Chokes, one of these has improved performance, the other is holding back performance. So it looks like some old components are going back, but new & other components will be changed, I have all the components here.

Remember: this is the same CPU I could not get 2.9GHz out of, look where it is now and this is not my best FX-60, that's yet to come..

The focus today, is to find a clever way to cool VRM & further motherboard components updates.

UPDATE:

The two screenshots I drop the voltage in the BIOS, the higher speed was set to 1.55v and the other was set to 1.5v.

Its the "lower voltage" that improved here, the CPU has never operated at that speed with that voltage, so some modification(s) to the motherboard has changed that.

Just in case you missed this, this is how a ASROCK 939A785GMH/128M cooler bracket now looks like. it cleans up air flow around the CPU & cools VRM/Ram better. ..Its working very well here.

After checking, "Mandatory" 3 bolts per side on modified bracket/holder must be used. ..six bolts in total is required.

You can still find the correct brackets if you look hard enough. I have at least 2 here. I do use them for a waterblock. A couple of the old Koolance blocks work perfectly.
Incidentally, the Thermalright XP90 and XP120 heatsinks use the same type of mounting bracket.
When you mod stuff, you have to think outside the box.

I have order some 478 backplate, I have a feeling I may need them in the future. Thanks again for the info.

It's pretty much a known fact that in 939 temps over 50c introduce instability. Object is to stay below 50c for best results.

No. 2000Mhz is ridiculous. I have seen over 1300 also, but rarely. 1000 +/- 100 is a good spot. There is absolutely no benefit gained by clocking the HT link. You only risk more instability by doing that.

Garbage. You need to test your ram then. According to your screen shot, you 're running Corsair PC3500 ram. That ram is made to run @ 233 FSB @ stock voltage and timings. You're running looser timings than stock so you should be able to clock a little higher than 233. If the ram won't run at stock speed, timings, and voltage, then it's no good.

Do not pay attention to what the ram says, only the speed & timings are real, That is a edited SPD that I did not correct.

I am working on temperature, but I won't get it below 50c on air at that speed. Even if I did, the Nano & VRM would raise case temperatures and push it over 50c easy.

The only way is to go water cooled or something, to go below 50c.

You can edit the SPD all you want but that does not change the manufacturer name or rated speed in which it was originally binned.

I can edit anything in the SPD, I can put my own name in there if I want. ...I can even lock the SPD.

Maybe so, but I know you didn't. The only reason you're mentioning it now is because I called you on it.
Pictures speak a thousand words. That is why we ask for them.

Some posts ago he actually showed a picture of one of his RAM modules' SPD showing his name (instead of brand, etc.).
But again, it may be just a tricked picture (like when they did that "new" A10 Hexa-Core APU picture to troll)

EDIT: Now i can't find it, but i recall seen a screenshot of CPU-Z's SPD tab showing "Delshay Memory" written in the SPDs. Maybe he deleted it.
EDIT 2: Found it: http://www.overclock.net/g/i/2836551/a/1531393/the-socket-939-appreciation-club-and-knowledgebase-official/sort/display_order/

I did put my name in the SPD, & in CPU-Z it clearly showed my name, what you saying I can prove you wrong.
