AMD® Phenom™ II Overclocking Thread

well both but more with the light switch on the wall .

also sometimes happens if something is turned on/off by a plug socket or light switch on the well in another room, e.g kitchen, living room.
 
spikes in the electrical system? - Tried using a surge protector gareth? Some PSU's can play-up if the voltage flickers, especially if your overclocking and drawing allot of power. ooo - I just noticed you got a Tagan PSU- i used to get a similar issue with my old old old Tagan, using a Surge Protector definately helped.

Woke up this morning to find Prime95 had stopped responding again - well at least it did slightly better than the previous times i run it - so I'm pretty sure its memory related. Probably will wait for a new BIOS revision , and run MEMTEST on memory sticks to ensure they are ok, before OC-ing now :(

I noticed someone recommending the baram with 2x apache fans. I have the same but only 1 fan. Any one know how much difference the second fan makes?
 
This is a really helpful thread, somebody had asked about monitoring cpu/nb volts, I have a Asus M4A785D-M PRO saw cpu/nb screeny of asus turbo V EVO, not listed on the utilities page for my board, got it from one of the new 890 chipset boards and it does indeed work, the only glitch with it is that it displays cpu volts incorrectly.

I have a x2 550 one of the early ones, would unlock to 4 cores stable only with xp sp1 any other os and it would not boot, this was in a Biostar TA790GX. I thought I would try the asus and I can unlock it to tri core with any os.

it seems like a spike but i have a surge protector already on the pc.

it happens at stock too

also i've had the electrician guy out 2 times to check my house but he couldn't find anything wrong, :confused:

try lowering your ram speed

do you have a 2 story house if so does it happen if you switch a socket/light switch on another floor if it does it would suggest a return to earth fault in the house wiring also switching a light switch should be on a different loop to the plugs so i would say it a earth fault.

the electrician should have brought a big yellow box around and plugged it in and it will tell him if there is sufficient earth to the house or not.

failing that could be a faulty RCD thats not quite tripping but has just enough effect to trigger a reset in the PSU. If you go to the electronics shop near st georges retail park you can get a plug in wall monitor it saves all the data so would also show any spikes in the amps,volts or load

What benchmark scores to these chips get too in things like Vantage cpu, SuperPI and Fritz Chess Benchmark? Would be interesting to see how they compair to intel chips of similar price
 
are loads of threads on this :)...

But in quick summary

generally the consensus is.. limited difference in games between C2Q, PII and i5/7... certainly not something you would notice day - to - day

In multi-thread apps i7 wins out typically by around 20% over i5/PII..
i5 probably has a slight edge over PII in multi-thread, beating PII in more benches than it losses in.. but the differences are small.. typically less than 2/3% either way, again not something you would notice day - to - day

Price wise.. for CPU / Mid-Range MB and 4/6GB of 1600mhz RAM

i7 is around £600.00
i5 is around £450.00
PII is around £375.00

(Note: These are "average", using average boards / RAM, etc.. I realise you can spend more or less on any of these set-ups but am trying to be "fair" and "sensible" here)

So if you are looking to buy in general I would suggest the following:

Multi-Tasking Applications: i7
Gamer and Multi-Tasking: i7
Gamer Dual GPU: i7 or PII
Gamer Single GPU: i5 or PII
Budget Gamer: PII (or look at the other AMD Tri/Quad cores some really good options here)

thanks. I was looking for something more on the lines of 3dmark/vantage/fritz benchmark screenshots though. I had a look through a few pages on this thread and couldnt see any
 
Are loads about.. AnandTech Bench is probably a good place to start if you want to compare across the board.. I would never recommend a purchase based on looking at one or two synthetic bench marks...

In terms of the ones you mention:

SuperPI: Intel CPU will always do better as its optimised for Intel architecture
Friz: i5 outperforms PII from what I have seen
Graphics: PII does especially well at high res compared to i7/i5, in fact it weirdly in a number of reviews it gains performance at higher resolutions. At low res i5/i7 tend to do better

But again a lot of the benchmarks / reviews you see are pointless as they aren't comparing like for like
