AMD Zosma 960T/1600T/1605T CPU Club - Page 35

post #341 of 2790
I don't really want in the club or anything, but I picked up a 960T for my son over the weekend and we built a computer together. He is 12 years old and has to earn this new PC with better grades.

It unlocked to an X6 and has been folding at 3.4GHz for the past 36 hours. I ran prime when I launched it after the unlock for 30 minutes. I think the folding time proves it is plenty stable enough to be a satisfactory X6 unlock.

Unable to get past 3.4 GHZ. without BSOD running any stress test. Tried the following, but crashed.

CPU Clock Ratio [X18] 3600 MHZ
CPU Northbridge [X12] 2400 MHZ
HT Link Frequency [AUTO] 2200 MHZ
Memory Clock [AUTO]
X6.66 1333 MHZ
***SYSTEM VOLTAGE OPTIMIZED***
System Voltage Control [AUTO]
Normal CPU Vcore 1.45 v

If I set the System Voltage Control to [Manual] then it shows the Normal settings as follows:

CPU PLL Voltage Control 2.5v
Dram Voltage Control 1.5v
DDR VTT Voltage Control 0.75v
NB Voltage Control 1.2v
NB/PCIe/PLL Voltage Control 1.8v

Only works when CPU clock ratio is set to [X17] and Northbridge set to [X12] or [AUTO] which gives 2400 MHZ either way.

CPU Performance Boost [Enabled] and under that listing it says
CPB Ratio [AUTO] 3400 MHZ
Turbo CPB [DISABLED]

Tried [Disabled] for CPU performance boost. No difference.

Any ideas?

Thanks,

John

Hello John,

must be frustrating. could you follow the steps in post#331 to the letter except the C&E is C1E?

That's better biggrin.gif When it comes to rendering (Sketchup + vray), it's almost 50% faster than my old 955.
Right now I'm trying to get a stable 24/7 clock ~4GHz with cool&quiet etc. enabled.
I use a 212+ with 2 Scythe Slip Stream 140mm fans in push/pull-config for cooling. The max CPU temp I've reached is 51 deg. Is that too high?

Welcome! i notice your vcores. your chips may be sweating. can you lower them 1.4v for the quad and 1.42 for the hex? might be able to go lower. i know it is colder in that part of the world rightnow.

1.5V for your vcore is a tad high. 4.0ghz should run with 4 cores around 1.4v (+/-.025), and with hex (assuming all work well), around 1.425 (+/-).

Well unlocking didn't work for crap lol I enabled UCC (mine is an ASRock board) and the board titled my cpu as "AMD Unknown CPU" or something along those lines. I enabled core control, disabled core control, restored default clock and voltage, upped the voltage, dropped the voltage, re-enabled all the default features and got nada. The board couldn't identify the processor with UCC enabled and Windows wouldn't boot.

Disabled UCC and restored 960T stock settings and Windows booted right up. Restored my previous overclock settings and everything is back to normal.

...I knew I wouldn't be patient enough to leave it alone for a week lol

Tried some more overclocking. Tried to just jump up to 4.5Ghz with a few voltage bumps, that didn't work lol

Couldn't get 4.3 to boot Windows all the way, even with the voltage bumped over 1.4.

4.1 I got to work without adjusting the voltage from my current clock, so I've come to the conclusion that if I do want to overclock beyond 4.1Ghz it's going to need a lot more voltage if it's going to work at all. And that's something I just don't want to try right now.

4.0 @ 1.375 it is for now. The voltage requirements for 4.3+ make me unsure if 4.1 would be stable, and perhaps even my 4.0 might not end up stable in some time. Gonna wait and see if 4.0Ghz stays stable.

At least my temps are staying good biggrin.gif 42° or lower all the time

may i suggest you follow this guide . . .

reaching stability may require adjustments to other settings other than the multiplier and vcore. overclocking beyond 4 GHz would definetly require minor adjustments to the cpu/nb setting as well as with the load line calibrations.

The voltage does not scale anywhere close to linearly. You can jump straight to 4.0ghz on about 1.375/1.4, but after that, it really starts to suck it up. 4.3 @ 1.525 is about what I get. I've tried 4.4, but regardless of voltage, the system just locks up. This is probably not a voltage issue at all. IMC is the likely culprit. Still trying to iron out some of the specifics.

Right now, I'm going through a very long and tedious process of isolating poor cores. I want to find out why these 2 cores were disabled. So far though, I can't figure it out, lol.

Arctic Cooling Freezer 7. Temps stay below 51 degrees C.

Well, couple of things I'd do.

First, drop the northbridge frequency and ht link to 2 ghz. no reason to have them higher than that. Disable CPU performance boost and turbo.

Set ram timings manually, you might want to increase the latency a notch or two just to ensure stability at higher settings.

You shouldn't require any vcore increases until about 3.7-3.8 ghz, but nb freq of 2400 might already need more voltage, that's why i'd set it to 2000, since that's it's native freq. the hypertransport link i'd set to 2000, as of right now, since that too is it's default. those should be the last 2 things you increase, after you've determined what the processors wall is.

51 c is the socket temp? or the core temp? if that's socket, then your cores are likely around 43C or so. Not bad, but you might want to consider some better cooling. Mine run about 26C loaded with my dark knight on there. VRMs/Mosfets might be causing some issues too if you have poor or no active/passive cooling on them. usually the chipset temp is referring to them.
