|Update - mboard model names corrected in this. |
I am typing this on a system with an EP-MVP3G5, the last and best one in Epox's series of MVP3 mboards. I have a K6-III 450 on it. I bought it new in Dec. 1999 and have been using it ever since. A have a system with a faster mboard and cpu I use for XP, but I use this system with this mboard the most. It's a full size ATX mboard, has two built in USB 1.1 ports. It has the last and best revision of the MVP3 chipset - it supports ATA/UDMA 66.
My Dad is using an EP-58MVP3C-M (AT mboard) upstairs connected via a wired connection to my router downstairs.
Epox has had serious financial difficulties in the last few years and I don't think they're making any new mboards anymore.
The www.epox.com site has always been slow loading for me, and sometimes in the last year or so it won't load for me at all.
If you actually do have EP-MVP3C2,
get mvp3c.pdf here:
That's definately a Super Socket 7 mboard, and it's manual is dated 1999, so it probably first came out in early 1999, not 1998.
You would probably have no problem running a K6-2 550 on it, since the EP-58MVP3C-M upstairs is running fine with that, and you MAY be able to run a K6-2+ 550 (they were made for laptops, use a lower core voltage) at 600mhz - all K6-2, K6-2+, and K6-III cpus interpret the X2 multiplier on the cpu itself as X6 - since I can do that on the EP-MVP3G5.
If you have the EP-58MVP3C-M, PM me and I can send the manual to you.
The ram info in the manual is incorrect. Each ram slot can use up to 256mb modules, but they MUST have 16 chips, not 8. You can find the correct 256mb modules by searching for ram for mboards that have the MVP4 chipset.
The only reliable working Epox site left is the Epox Store in California.
They're attempting to sell off the remaining Epox mboards, and other Epox parts, but most of the listed mboards are sold out.
A bonus is you can order a new bios chip for any of their models that had a bios chip in a socket, with is most of if not all of them, flashed with the last available bios version, for only $10 plus shipping. To see the list of mboards the bios chips are available for, you have to go through the motions of placing an order - if your model is not listed, email them - they can probably supply it.
They ship to Canada as well as the US, but when I ordered a mboard from them (I'm in Canada), I was charged extra by UPS, GST and a handing charge were added on, and the shipment sat in a warehouse for several extra days, once the shipment crossed the border. (That's typical for when someone in Canada orders from a US web site, except for from www.newegg.ca, which uses a special UPS shipping method to ship to Canada.)
According to my experiences with the EP-MVP3G5 and EP-58MVP3C-M.....
- the Award bios version MAY have a bug or bugs that prevents Standby from working correctly. You'll know whether it does have the bug or bugs the first time it goes into Standby mode - it won't come out if it.
In that case you can make do by disabling Standby. In ME and previous, run msconfig - look at the program listed under Startup - disable both "load power profile" lines from loading.
In 2000 and XP, go to Control Panel - Power Options and set System Standby to Never if it isn't already set to that. Similar applies to Vista and Windows 7.
You can still set the Power Options to turn off the monitor and hard drives in xx minutes - that will work fine - merely moving your mouse switches it or them on again.
- the Award bios version may have a bug or bugs in it that prevents hard drives larger than 32gb, or 64gb, from being recognized as their full size, or that freezes the intial boot at the point when the bios is detecting a drive larger than that.
There is a later bios version, which I have, for the EP-MVP3G5 that fixes that, and there is a bios version for the EP-58MVP3C-M, which I have, that was patched by a third party to get rid of that problem. If your mboard actually is EP-MVP3C2 there MAY be a patched bios version for that that I could dig up on the web.
In any case, the Award bios version and the MVP3 (and MVP4) chipsets cannot recognize the full size of any hard drive larger than 128gb in Windows and the bios / = 137gb manufacturer's size - they see it as 128gb. If you need to support a hard drive larger than that, get an inexpensive PCI IDE (a.k.a. EIDE, PATA) drive controller card and connect the drive to that (or a PCI SATA drive controller card if you like) , but if you want to be able to support connecting CD or DVD drivesto it, the description must say the card's chipset supports ATAPI, and/or ir supports connecting CD or DVD drives to it.
- the amount of ram that is cached by the L2 cache chips built into the mboard is directly dependant on their size.
E.g. My EP-MVP3G5 L2 cache chip is 2mb - it cachesup to 512mb of ram. Older models have a smaller L2 cache chip.
If you install more ram than the L2 cache capacity can cache, NONE of the ram is cached, and you take about a 40% performance "hit" regarding the performance of the ram.
- the K6-III and K6-2+ (and K6-III+ but I've never come across one) cpus have an L2 cache built into the cpu. If the bios version supports recognizing the cpu type that has that L2 cache in the cpu, the L2 cache built into the mboard is used as an L3 cache, and the cpu gets a performance boost that is equivalent to you having a faster cpu. If the mboard manual mentions K6-III cpus, even the original bios version probably supports recognizing them properly. K6-2+ and K6-III+ cpus, which were made for laptops and use a lower core voltage, came along later, and some desktop mboard bios versions don't natively recognize they have a L2 cache - in some cases there are bios versions available that have been patched by athirdparty to support the version recognizing K6-2+ or K6-III+ cpus.
E.g. On the EP-MVP3G5, with the last available bios version, Sisoft Sandra rates the
- K6-III 450 with the multipier set to X4.5 at 100mhz (450 mhz) as equivalent to a cpu running at 541mhz.
- K6-2+ 550 with the multiplier set to X2 (= X6 on the cpu) at 100mhz (600 mhz) as equivalent to a cpu running at 721 mhz
(so the last bios version does recognize K6-2+ cpus properly).
