D3ATHKeeper Posted November 27, 2012 Share Posted November 27, 2012 Hello there I figured out a few days back my games isn't performing as they should be performing, and I wanted to no is it my CPU that is bottlenecking or is PSU not giving enough power to my system. I think its both, I tested this with Need For Speed: Most Wanted 2, L.A Noire, Prototype 2 and my Skyrim is a bit laggy so my specs are: CPU: Intel Celeron D 336 2.8GHz over clocked to 3.6GHz GPU: Asus Radeon HD 7770 PSU: 350W I now my GPU needs at least 550W to run at full load (The Radeon website says it needs 550W to run at full load) so please give me your info on this topic. Thanks in advance :thumbsup: Link to comment Share on other sites More sharing options...
D3ATHKeeper Posted November 27, 2012 Author Share Posted November 27, 2012 Sorry forgot to tell you the games I talked about it takes almost forever to load up Need for Speed freezes on a white screen and Prototype 2 crashes when they start talking bad stuff and I have to restart my hole Computer because of Prototype 2. Only Skyrim doesn't take forever to load up. Link to comment Share on other sites More sharing options...
FMod Posted November 27, 2012 Share Posted November 27, 2012 (edited) PSU can't bottleneck a system. It can die and it can destroy the system, if it's overloaded, but the system can not manage its power draw in regards to the PSU. Your CPU is... Sandy, Nehalem, Core 2, predates that - yep, 3 major generations out of date. Or 6 if you count minor ones - Sandy->Ivy, Nehalem->Clarkdale, Conroe->Penryn. These included two architectural revolutions, Core 2 and Nehalem.And unlike Athlons, old Pentiums didn't age nicely. It's a single core Prescott celeron that has... at best it could have half the performance per cycle of a modern core. And the practical result is even worse; it has only 3 LinX GFLOPS. Overall it has about 1/25 to 1/16 the performance of top modern CPU depending on the task. And, at 84W TDP without any real power management technologies, it's costing you a pretty penny to run, even by US prices. You certainly should replace the PSU when you get the chance, with something from a decent make, because I suspect your 350W is just "it came with the case", but the CPU is your most serious problem. How much can you spend? Edited November 27, 2012 by FMod Link to comment Share on other sites More sharing options...

D3ATHKeeper Posted November 27, 2012 Author Share Posted November 27, 2012 O and I now my PSU can't bottleneck!! Sorry if I sound rude Link to comment Share on other sites More sharing options...
Dan3345 Posted November 27, 2012 Share Posted November 27, 2012 Yes its your CPU. what FMod is saying is that your powersupply isn't actually connected digitally to any part of the computer. The components do not talk to the PSU like they do themselves. So if your PSU was throttling down the voltage to your CPU, the computer would just crash and shut down.

kalikka Posted November 27, 2012 Share Posted November 27, 2012 550W for 7770? dont make me laugh, the manufacturer recommendations are pure bs. They are meant for chinacrap like this bomb.Power peak values of 7770: 73Whttp://tpucdn.com/reviews/HIS/HD_7750_IceQ_X/images/power_peak.gif Link to comment Share on other sites More sharing options...
D3ATHKeeper Posted November 28, 2012 Author Share Posted November 28, 2012 (edited) Ok thanks for your help I will upgrade my CPU :biggrin: Edited November 28, 2012 by D3ATHKeeper Link to comment Share on other sites More sharing options...
