AMD FX (Bulldozer) Owners Club! - Page 796

post #7951 of 8112
I would like to share this with you guys.
Its a spreadsheet i made in my quest to reach the most efficient overclock. thumb.gif

Key things
- It gives (starters) an idea of what voltage is needed for witch speed
- It proves the importance of LLC and the right setting. tongue.gif
- Starting with an under volt gives optimal results.
- Undervolting is great for the FX!

AMDfx8150.xlsx 20k .xlsx file


Question: Should I replace my FX8150 @ 5.1ghz with the "new" FX 8350 or wont I see any noticeable benefits? biggrin.gif

Iam not sure ive never owned a 8150 I have a fx 6100, fx 9370 and a a10 6800k. I would guess no not a huge gain your going from a 8 core chip to another 8 core chip, but then again they did tweak the cores for more performance so you might see gains in certin applications and games, not sure. I would hold on to that chip you have I think its way more then capable at 5ghz. My 6100 tops out at 4.2 ghz max. Yet to test my 9370 cant wait!

Not worth it. Keep what you have and wait for something better. My 8150 tops out at 4.5 with that same exact board..

Thanks for the thoughts guys.
(Patricksignlin: I'm on watercooling, this chip maxed out on stock HS arround 4.6.,
Also cool you VRM's that makes a huge different in CPU temps to!!)

I think i might have a semi-golden chip, that is holding me back to upgrade. I did 5.3 Ghz with something arround 1,575 volt buth it just dropped out on me, i assume the powersupply cant handle the FX at that speed and amps. (It tried to pul 600+ watts from the wall and i only have a 650 PSU)

the 8350 is +- 10 procent per clock faster than the 8150 (if IRC), but if i'm unlucky with the new chip it wont clock so high.

Think i will going to stick with the 8150 for now.
Mayby a new PSU and pushing this chip a little more would be more fun biggrin.gif

What power supply are you running Nightwolf? 10% increase in performance may sound good on paper but I seriously doubt you will notice a diffrence in everyday tasks and gaming.If your looking to increase gaming performance just upgrade your Gpu instead. Besides theres no gurantee if you get a 8350 it will clock as high as your 8150.I would hold on to the chip If I were you. Thats a pretty good overclock you got out of it!

600 at the wall so you are no where near. 650w SUPPLIED to the pc not from the wall.if i had to guess you just need more volts, no where near stable

Its not your powersupply. Its your chip not being stable at those speeds and voltage. Also a 650 watt rated psu can draw 780 watts from the wall or less or more depending on its efficiency. A 650 watt psu that is 80% efficient will give you the 780 watts figure. Kilowatt meters are not super accurate either.

Also I went from a 8120 to a 8320, cost me around 30$ to upgrade after I sold the old chip. Its a upgrade, and its a decent upgrade over the bulldozer processor. I ran my 8120@ 4.6ghz daily, it could do 4.9ghz tops. The newer 8320 runs at 5ghz daily and has a 5.3 ghz or higher max, my board lacks the proper llc to provide that much power stability to it to find out. Apples to Apples at 4.6ghz to 4.6ghz the 8320 is anywhere from 10-20% faster.

Okay good to hear, thanks a lot! Will push the volts a little more when I have time biggrin.gif
Yeah would like to go to 8320 or 8350, but i was already lucky with this so i fear that i wil have a bad 8350 that wont clock as high rolleyes.gif

It's a Corsair TX650, rated 80+ efficiency . I have gtx 760, was thinking of going SLI with it next year, if the PSU can cope.

Also I went from a 8120 to a 8320, cost me around 30$ to upgrade after I sold the old chip. Its a upgrade, and its a decent upgrade over the bulldozer processor. I ran my 8120@ 4.6ghz daily, it could do 4.9ghz tops. The newer 8320 runs at 5ghz daily and has a 5.3 ghz or higher max, my board lacks the proper llc to provide that much power stability to it to find out. Apples to Apples at 4.6ghz to 4.6ghz the 8320 is anywhere from 10-20% faster.

Where did you draw that conclusion from?

you answered your question

780*.8 =624 so slightly off but meh

most averages psus are ~ 80%
