How high are you able to push your i3-530?

I've just put together a new system based on the Gigabyte P55-USB3 and Intel i3-530. Mine is running very stable at 4519 and I was just wondering if you are getting similar results.




Thanks

I have my i3 530 @ 4.0ghz and 1.270 vcore. cooler is a hyper 212 plus so temps are around 60 during prime 95 so i dont plan on going any higher right now..

Yeah, I guess I should have added that I have the Scythe Mugen2 Rev.B cooler, and I see Prime95 temps hit ~64C @1.328V.

The highest stable oc I have achieved is 4.1 with the default multiplier and a vcore of 1.35, but looking at everyone else's vcore readings with this chip that seems very high. I may be limited by something else but I'm not sure exactly what to set some things at especially the VTT and PCH voltages. Can you please post some of your voltage settings for me? I am using an AsRock p55 extreme, Coolermaster Hyper 212+, and 4gb A-Data DDR3 1600. Even with the voltage set at 1.35 I have never seen the temp on either core go over 55 so I know I should be able to go higher but I am severely Bclk limited. I would love to see a Bclk of 200.

What speed is your memory at? If CPU-Z says 850mhz or above, which means your RAM is the limiting factor. You could just lower the memory multiplier and you shot be fine.

I am also interested to know what VTT and PCH voltages I should use, I have left them at stock. I am pretty sure, to have a high BCLK you must higher the VTT voltage, not too sure though.

You temps are good, what thermal paste are you using. I get up to 61 degrees during P95 and I'm running at 4.0ghz and 1.264 vcore.

My memory is at 930mhz at a bclk of 186 which is the highest I can go. My memory is memtest stable overnight at that speed (That ram is awesome). I bump the multiplier down to 4 which would give me 744 and I still can't raise the Bclk any higher. I do have the VTT and PCH bumped up from stock but I'm scared to go very far because I have no idea what it should be, for all I know my motherboard could have it set really high already on auto. when I get a chance I'll see what they are set at on auto. As far as the temp, I am using the silver cooler master paste that came with the 212+, but i have it in an Antec 300 case with 3 120mm fans, 1 140mm, and 1 80mm fan.

Maybe try lowering CPU multiplier and memory multiplier and see if BCLK can go higher, If it can then we know your CPU is limiting the overclock, not memory or motherboard.

I have tried damn near everything and I cannot go any higher on the BCLK, so maybe I just got a poor overclocker compared to other i3s. Don't get me wrong I'm not complaining about my current overclock, it's an amazing amount of performance for a $120 processor.

very impressive, what was the vcore at 4.2ghz??

Wow, You must have had a killer chip... 4.2ghz and 1.211 vcore, very nice.... Mine is unstable at 4.0ghz and 1.25 vcore, needs atleast 1.26 volts. any suggestions like vtt voltage and PCH voltage.

Whats your VTT at for 4Ghz?


I left it at stock because I am not sure what it is for. My BIOS has the option to bump it up in steps> +0.01, +0.02, +0.03 and so on. What should I select. Will this affect temperature?

With higher VTT it'll allow you to run less Vcore.



Should I higher the VTT the same amount I lowered the vcore? Say, vcore 1.264>1.250 and VTT +1.014 ??

I mean VTT + 0.014, in steps like that

I had an idea and I'm going to test it tonight, I wonder if turning off hyperthreading would help, and at what performance cost?

Be sure to post back results and let us know what BCLK, vcore and vtt voltage and temps etc.

You should run 3dmark vantage before and after disabling hyper-threading for benchmarking.

DO NOT disable HT



Why not disable HT? Even if it does cause a drop in performance we should be able to get a higher clock right?

I could get 4.9Ghz with HT enabled. There's no reason to disable it as you will take en enormous hit


If you disable HT wouldn't your processor consume less power thus, generate less heat which would allow us to get a much higher clock with same same heat and power consumption?
