AMD Overclocking Club

[johnnsti08]

Hi Guys,

Can you please assist me in my overclocking. I cant get my overclock stable.
Hardware:
Phenom II X6 1045T
ASROCK N68C-S UCC (95W Board)
Cooler Master 212+
4GB Kingston DDR3 1333 Value Ram (8GB [2x4] G.Skill Ares Coming in 12 hours)
Sapphire Radeon 7770
Omega 750W PSU (33A, +12V rail)

When I try to overclock, and run Prime95 @ 3.4GHZ, The computer shuts off by itself. Also if i try 3.1GHZ, the CPU speed is downthrottled to 1600MHZ and voltage is downthrottled. Cool and Quiet was off, C-State support off, Turbo Core off, Ram set to 1226Mhz, Voltage Manual, 1.35V. My max CPU core temperature at 3.4Ghz was 35 degrees. I heard some people talking about disabling 2 cores (This computer is purely for gaming) but im not sure if that will help it to become stable or reduce performance of the CPU. Based on other suggestions, it has been noted that my processor HT link is limited to 1000Mhz because my socket is Am2+.Yes I know my mobo isnt good, but i really cant afford one right now (Im still a student) Can anyone help me?

Your CPU is locked so, change FSB is change HT, NB and RAM frequency. Set your RAM to the lowest possible frequency and try to keep your HT and NB to 2000MHz or closest, rise the FSB in little steps and try. Voltage on Auto for now for CPU, RAM at 1.65V and HT and NB on Auto too

Let me know the results.

Just to clarify because im new at this, ram at 1.65(The 4GB Value ram that is), Ram at lowest frequency, (even as low as 500MHz? )NB at/or near 2000MHz and cpu voltage auto, FSB at maybe 225?

Correct. Lowest frequency I mean 1066MHz (533 on BIOS maybe) and try 1st with FSB around 215...

Ok so far prime is running for 10 minutes @2.96Ghz, ram at 800Mhz, Max temp 32 degrees. I noticed that it downthottles occasionally to 1.5Ghz at 1.16V then after 10 seconds or so it goes back to 2.9Ghz, then downthrottles again and vice versa

EDIT: ||

While i was posting this messgae up, the computer shut down after 15 minutes of Prime. Also i was warned against overclocking with my PSU.

"The PSU is the culprit. With that PSU, I strongly urge you to stop overclocking and stay at stock until you get a quality-made unit. If this PSU fails due to overclocking (which it probably will), then some of the following could occur:

The death of your PSU
The death of one component in your system
The death of your entire system
An electrical fire in your room"

I only had about 20 minutes to tweak because this PC is connected to the TV in the living room. I was able to run IBT for 15 minutes max temp 50C...

That's not any indicator of stability. You need test it more, around 2 hours for know if can be stable or not.

I know Saint, I didn't say it was stable, I did only have 20 minutes. I'll get it stable and maxed in due time.

Do you have the link of your PSU? The last options is almost impossible that happen as well as many of the others one.

Please give me the link of your PSU to check the specs and see if we can continue with overclock using your current PSU.

 

[johnnsti08]

Ok i dont have a link but ill tell you the specs

Omega 750W PSU
+3.3V 34A
+5V 56A
+12V 33A
-12V 0.8A
-5V 0.5A
+5VSb 2.0A

+5V 56A
+12V 33A
-12V 0.8A
-5V 0.5A
+5VSb 2.0A

how may rails on that PSU? my Guess is 2 as 33A is WAY low for even for an off brand 750W PSU. Also the +12V rail should have the most amps to it.

 

[johnnsti08]

I dont think so, it only says one +12V figure on the PSU label

 

[saint19]

Ok, PSU is crap.

A good PSU never have more (A) in the 3.3V and 5V line that in the 12V line.

use hwinfo32 or 64 to check voltage at +12 , +3.3 and +5v during your prime 95 test and furrmark test (simultaneously)
if they remain around that voltage then maybe psu is not holding you back (atleast now) (eg +12v should remain above 11.5v )

and for current games, you should dissable 2 cores and clock it as high as possible

or alternative is to use high turbo and low base clock (i use 3.2ghz@1.2v for base and 4ghz@1.425v for turbo for my 1090t on stock heat sink 😛 )
this way you have all 6 cores when needed but can turbo to 4ghz if single thread speed is necessary.

 

[johnnsti08]

Ok I downloaded hwinfo64 and i have no clue how to check the voltages. Also i have no idea how to disable cores, is there anyway you can help?

i tried unlocking and using hwinfo but it went bit unstable at 3.56 Ghz with 205*17.5
so i reverted only to unlocked cores with normal 3.2 Ghz and this is the status of it
Please do help if i can make any changes

new thread with full detail will be a better option

though, in short
check minimum values at +3.3v, +5v &+12v hwinfo32 sensor and make sure that they are above +3.3v, +5v & +12v respectively during intelburn test and furmark (simultaneously)
this means that your psu is correctly working

if the voltages drops down to ~95% (just my estimation) of rated voltage (eg 12x95/100= 11.4v) then psu is under heavy stress and may fail in near future

btw
if board only support upto 95w cpu only, then don't clock it much

I tried many different frequencies and finally got the best with stock fan 😀

CPU: AMD A8 3850 APU
Name: Gravito-PC
Frequency: 3600 Mhz
Vcore: 1.375V
Ref*Multi: 200x18
RAM: Corsair 4GB 1333 OC @ 1866Mhz
Temps: ~30C Idle, 15C-40C under 100 percent load
MOBO: Asus M4N82 Deluxe
AMD Radeon 6550D OC @ 933Mhz.

It's running like a charm OMG with stock fan got 20+ FPS boost in GTA 4 Huraayy!

 

[compgenie]

Is h100i enough to get a 6300 to like 4.2 or 4.4?

Getting a 6300 to 4.2-4.4 should be a breeze. With a H100i I think you can get more like 4.6-4.9 unless you get unlucky with your CPU and have a bad overclocker.

 

[compgenie]

^that's encouraging! Btw how good is the fx 6300 at stock and overclocked? Like a beast? 😀

Eh, about as good as a stock 1090T. It depends on the workload I guess. While Piledriver is a sizable improvement from Bulldozer, it's still not up on my list of something I have to have. If you already have a AM3+ board and you had a Phenom II that you're looking to upgrade, I could see getting a FX-83XX. If you're buying a new platform all together then I would probably go with something else.

Not trying to start a war as I realize this is an AMD thread but this is just my honest opinion.

 

[king smp]

Yeah I love my AMDs but my 1100T is as far as I am going to go.
I have an I5-2400 1155 rig also and I would spend the money on a CPU upgrade (2600k) and make that my main rig
There is just no denying that Intel is the performance/price leader right now.
Hopefully AMD will at least get the performance per dollar crown back in the next year or two but for now at any price point
for a new build Intel is the way to go.
The only exception might be in a workstation doing very heavily muitlthreaded work where a FX 83xx might have an edge

I fixed my 1055T rig! Have it folding at 3.5GHz right now. I think I can get 3.8GHz before I hit a temp wall. I'm not too concerned about voltage, I bought her to ride hard and put away wet 😉

 

[king smp]

actually a 1055T and a 1100T are the same chip just different clock speeds (different binning)
I have mine on a daily OC of 3.8ghz and I have had it stable up to 4.1
I bet if we run cinebench 11.5 both at 3.8 we would have exactly the same score LOL

 

[stickg1]

IDK, I'm using an AM2+ board so I have to use DDR2 RAM. That might have a role in overall performance.

possibly
I will do a run in a few minutes and post it here
since this involves two OCd AMD cpus I hope that is okay with the mods on this thread
