Mr.Ex.President said:1. Don't mess around with Microsoft. Get a Corsair, or a User brand...
2. For high-quality power supplies, the maximum voltage deviation shouldn't exceed 5% (if it does, you should definitely file a warranty claim).
3. I'm not entirely sure if higher or lower is better, but all I can tell you is that my Corsair unit keeps the 12V rail at 12.3V, the 3.3V rail at 3.4V, and the 5V rail right at 5.00V.🙂
Best regards,👋
Well, there you have it... that crappy 300W unit from Microsoft was already in there, carried over from my old rig. But the 3.3V rail is completely out of whack, sitting at a measly 2.78V, which convinced me it's time to find a replacement—something I'll be able to grab as soon as I sell off this old Crucial RAM and the rest of these components (hopefully making a little $150 🙂 in the process).
The 12V rail is giving me 11.85V, while the 5V rail sits at 5.08V. The real headache, though, is how the 12V rail drops the moment I bump the CPU voltage up to 1.8V or higher. For instance, at 1.8V it hits 11.67V, and at 1.825V it plunges to 11.55V, which is absolutely unacceptable; I'm pretty sure those numbers will send the whole system straight to an early grave.😁
By the way, I was thinking about just grabbing an EVGA 360W; they aren't expensive and everyone seems to swear by them. Or maybe something ultra-quiet... didn't someone mention a User brand or something similar? President, what are your recommendations? (I mean, you basically "built" this machine for me anyway)😁
Anyway... my latest deep dives into overclocking have yielded the following results:
- The peak overclock on this Apple Crucial PC3200 memory was achieved during asynchronous operation, hitting 219MHz (with the FSB at 182MHz). That was all on stock voltage.
- At 1.833MHz, the minimum voltage required is 1.45V; anything lower than that just produces a garbled mess.😁
- The minimum voltage needed to keep the processor stable at 2200MHz is 1.7V.
- The highest stable overclock reached was 2310MHz @ 1.825V; I didn't push any further because of the power supply (I'd rather not risk frying the entire computer just for the sake of being reckless).
Stability was tested using this specific sequence:
- Booting into Windows XP
- If it survives that, I run Prime95, 512K
- If it passes without errors, I move on to Prime95 benchmarks
- If it manages that without any glitches or crashes, I then run a 5-minute Prime95 TORTURE test.
Only if it clears all those hurdles do I declare it stable and consider it a candidate for a full 6-hour Prime torture test... eventually.😁
So, yeah... I ended up rambling on like some sort of overclocking guru.😁
