-5v is only needed for a couple isa cards that I know of like media vision, I know. Tho some boards apparently don't boot or work differently without it. I see that there is the Voltage Blaster, and apparently there are some connectors that I believe either have DC-DC converters, -/+ inverters, or …

It's a cut-off point for 256Mb VRAM on high-end GPUs. Sure, that holds up even today (well, in gigabytes). More PCIe bandwidth won't fix that completely. Well, on 8800 320mb it will, hence the whole "investigation". So on such a platform (P4 3.x Ghz, 775, AGP+PCIEx4), what's the highest GF series …

My current plan (pun intended) is to keep a small collection of old ATX 1.x PSUs and refurbish them, as needed. Soldering a cap is one thing, refurbishing a high voltage component such as PSU is a bit next level. It also creates a "hobby inside a hobby" with all it's drawbacks. And you can only …

Why do you care so much about -5v? Do you really care about super early sound blasters? Frankly, this is my most period correct PC (mobo is maybe from 2000, but I got it for cheap and it's a fully pre-P4 board). Now I'd take a new ATX supply over any 20 year old one without thinking, but look at it …

It's not that complicated really. Just like Doom 3, Quake 4 has uncompressed textures on ultra settings, so of course it won't fit into 320mb. And COD2 just has more detailed textures and bigger levels. Latter was discussed a lot , because that game quickly made 256Mb high-end cards obsolete ( …

The relatively large GeForce performance drop at 4x is curious. There was some strange behavior with the 320MB GeForce 8 cards that may have been some kind of driver memory management issue. I think it was eventually fixed. I think it's pulling texture data across the bus when it shouldn't be …

Lastly, you can't "disable" one of the dies of Pentium Ds in 90% of LGA 775 MBs (and only Intel manufactured ones, usually have this option [if they support multicore CPUs]). At best you can soft-disable either one from OS (msconfig/Advanced/CPU Processors selector). But this doesn't power off the …

A bit of a necro: This 1999 PC is a fully 3x ISA equipped s370 MOBO with 20-pin power supply that supports -5v. It's also chock full of cards and disks. Where can I get a semi-decent pre-ATX12V 2.x PSU? (no USA amazon links) I see there is that PCI Voltage Blaster solution for -5v for modern …

That's not how it works. Once again, read PCIe specs. I know, I said maybe, I've read somewhere that it was an issue, maybe exclusively with these PCIEx4 + AGP combos, I probably mixed the issue with fake AGP not being able to provide enough power (since it was really a hack of PCI slots and extra …

Availability of any of these will be limited but of the three the 661 will be easiest to get and cheapest, the EE editions can be very expensive with the Fire starter 2m being exceptionally painful to buy. The 965 should work in any late 775 Pentium4 motherboard that has a VRM that can handle its …

Gallatin L3 didn't help at all for gaming or cache dependent tasks, it was slow cache and unable to be used in the same manner that L2 cache is. Gallatin was roughly 10-20% faster than Northwood due to the L3 cache and had it been fast L2 that performance increase would have been larger. CM stopped …

At Toms Hardware If you read how they did the PCIe X1, X4, etc they taped parts of the vid card and only a few select boards could even work with things that way (leading me to think their method was an improper way to get real world results). AFAIK gtx680 could possibly need to draw more power …

Yes I can explain. Thanks, but that part I'm familiar with, it's the starvation of GPU performance shown here: https://www.tomshardware.com/reviews/pci-express-scaling-analysis,1572-8.html that was explained that the 8800 doesn't have enough VRAM, so I'm guessing has to transfer needed textures …

That's synthetic benchmark - not relevant. All the benchmarks make both cards fail more or less, and one game kills 8800. I'm not here to contradict you, but knowing that your weak lane will bite you someday is OK thinking, but knowing which combination of game and GPU(VRAM) is impossible, hence I …

I would not stress this in 2022. 640mb variants are common and someone could test the differences between them. I use sometimes G92 8800GTS 512mb on 775DUAL-VSTA, from what I have gathered it has ~15% lower performance for some reason 3dm06 score of 10k vs 12k of similar pcie x16 systems but it …

That actually proves my point: 8800GTS 320mb (not enougb VRAM) = bad performance. X1900XTX 512mb (enough VRAM) = good performance. So, if you've low on VRAM, more transfers happen on a slow PCIEx4 and it chokes FPS? I mean, GTX680 isn't really low on VRAM, even if it's running those modern games, …
