Hello Overclockers!

I've been asked kindly to move my post here by Conumdrum.
Mod's, feel free to delete post /forums/showthread.php?t=725798.

I'm looking for some help on making sure I get the most on my current build. So far I've done minor adjustments and achieved from 3.3 to 3.5 ghz on my AMD 1055T.
Today I've been fiddling around in trying to reach 3.7ghz but, I feel I might need a little bit more help on voltage/memory timings if possible as it is unstable after a few minor tweaks I do.

Specs:
AMD 1055T
Corsair Hydro H60 CPU Liquid Cooler
BIOSTAR TA880GU3+
BIOS American Megatrends 03/23/2012
G.SKILL F3-12800CL9-4GBSR 9-9-9-24 (x2 4gig)

Current clock/Voltage
Core Speed 3500Mhz
Multiplier x 14.0
Bus Speed 250.0
HT Link 2500.0
Core Voltage 1.548V

Timings/voltage
1.60V
1333mhz
DRAM Frequency 833.3Mhz
FSBRAM 3:10
CL 9 tRCD 9 tRP 9 tRAS 24 tRC 33 CR 2T

I would appreciate any help possible and if you would like more information, please ask an i'll provide what I can.


Thanks in advance,
Gen



Hours Later that day:
Alright, I got the Hyper Transport to 2250 (plier x9) and most of the voltage are on auto.
Do you guys think the motherboard is holding the CPU back? if so, what suggestion boards?
 
If it takes this > Core Voltage 1.548V to reach this > Core Speed 3500Mhz

and you have this > DRAM Frequency 833.3Mhz

and CPU_NB is equal to or greater than this > Hyper Transport to 2250.

Then you are probably done for anymore speed. Some have even clocked short of your 3.5Ghz here lately. In most applications a 955BE or 965BE clocked to 4.0Ghz would be more powerful than that locked 6 core with such a small multiiplier.

Mmhmm... I seee...but (a bit confused), I don't quite understand how most people can go just a bit below 3.5ghz when I've came across CPU-Z's on hitting 4.0ghz on a plier of 14, bus 286 ,HT2002.1 mhz. What is holding back on mine? or were they fake reports? I'd love to hit those speeds if it takes replacing a board and more.

Forgot to add, the core voltage was manually set up. Leaving it on auto will crank it down between 1.47 - 1.5.

*note:I'll be back shortly, I'm going to place back the 3.5ghz clocks.
 
ok, here is a clip cpu-z. vCore is 1.452.

Well CPUz validations don't prove much. They are more like just moonshots. Once and done. Maybe those are what you were seeing at 4.0Ghz. And yes there were some CHlV Asus motherboards that could push 250 plus FSB but the memory controller inside the cpu has to be able as well. If your cpu is as bad as some we have been seeing in the AMD Cpu section lately, then you will not get any closer to 4.0 Ghz than you are now.

Why are you not trying 255FSB or something that is not a giant leap and see if that gives a little more. You have to watch the ram speed though since it rises with the FSB as does CPU_NB and HT Frequency.
 
That's a great board, I have the same one in my rig. I'd say target your NB speeds and memory timings as opposed to max FSB. I run my rig 24/7 with a 3000mhz nb.
 
Ok well I can't go 255. I even had to take off some voltages from automatic and go up 0.05 a couple times and nothing, it took 253 though.

To get it to run, I have the NB speed on 1600(of 2000) and timings are 9-9-9-24 @ 1333mhz. I tried 8-8-8-21/20 and a couple different others it was a no go. Do I also have to lower the NB speed even more or is there more to it?

Also, I've chosen to increase FSB over NB/memory because my plier on the cpu only goes to x14, did I chose right? or you think i should still try the other way.

*edit when i first built this PC, i was able to place 1600mhz (overclocked) on the ram. That was when I had the CPU on stock speed of 2.8ghz.

Depends, sounds like you will get more out of the fsb increases since you can only go 14 on the CPU. You could try the 200mhz fsb approach and run some benchmarks to really get a better idea.

Well so far I was able to tighten my memory timings and everything seems more snappy, even windows 7 loaded faster.
My only concern right now is how the memory is set.

Previous 1333 mhz 3:10 ratio on a timing of 9-9-9-24 T2

Current 800mhz ratio 1:2 on a timing of 7-7-7-15 T1

Should I try increasing the bus even more now?

Update: CPU is stable at 3640.40Mhz

Target is 3700!

Great! Try bumping your CPU_NB voltage up to 1.3 and bump up the NB multi to put the NB speed in the 2200-2400 range. That should help with memory throughput. Also, under memory settings, you can try to go down from 110ns to 90ns, be careful though, it may cause a no post setting. But the good thing about that board is it will post after a few fails, and you wont need to reset everything all over again.
 
Well ...i'm surprised... check this out. But! I have an issue, I can't get the HT link to 2000 when I go over 280. I'lll increase the NB VID to 1.3 since its currently 1.2 and NB Speed as you mentioned.

Edit: and thanks for your help, much appreciate it.

Thanks! increasing the voltage and NB_F from 1400 to 1600 is on the money!
HT Link 2240mhz!!!!

Going to run some stress testing over night.
 
That's looking good! Almost 4ghz...
You should be all set with the HT link, no performance gains to be had at all from stock.

I assume your NB clock is 2240mhz as well? Try bumping up the multi on that and your system will really fly. Mine is solid for daily use at 3000mhz, but some can only get 2600 or 2800 on this board. Some slight voltage adjustments may be required. Here are some voltage references you *may* be able to use, from my 200mhz config on the same board. Use your specific memory voltages, etc

I'll double check but I think my NB FID is currently at 1600, max for me is 2000 where your 3000 is.
 
Ok, this is the end result. But man!... I can't get that last couple Mhz for 4.0 haha!
This is good enough, thanks for taking the time in helping me out.

Good morning fellas,

Well just messed with my memory timings because I felt like applications were a bit sluggish even though my windows loads freak fast now. So went from 800mhz clock timings of 7-7-7-15 (533mhz)to 1066mhz 8-8-8-20 (744mhz). At first had the 8-8-8-20 on 800mhz and figured I bump it up one step to see if my machine would accept it.

Any thought and do you think I made the right decision?
 
Alright, so I diffidently feel a slight performance decrease when playing games and using varies applications. I would like to achieve memclock value to be at least 1066 and if possible 1333 (currently 800mhz with timings of 7-7-7-15 or 8-8-8-15)

Any help would be appreciated and i don't mind sacrificing some Ghz since its already at 3.9.

Thanks!

Fixed my issue with the memory value being 800mhz instead of 1333mhz.

So that's 3.9ghz FSB 280 Core voltage1.488v NB_VID 1.3000
Mem value 1333

Memclock Value:
DDR3-1333
CAS Latency - 8
2T Command - 2T
TRCD -8
TRP - 8
skip
TRAS - 24
1.65v

I am seeing a discrepancy in what you are reporting for actual memory speed. CPU z pic (the memory tab, NOT the speed tab shows actual memory clock speed) you posted reports your memory running at only 585mhz, which is equal to about 1100mhz, not 1333mhz. Check your CPU:FSB multi to get more out of your ram. Seems like pretty high performance ram, so if you aren't running at a full 800mhz (again viewed in the memory tab of CPUz) you might even try for 1t timings.
