I'm looking for a site that has technical information on the GA-7VXRP. What I'm most interested in is what type of RAM it is capable of running. I know it runs DDR, but I've seen conflicting reports ranging all the way from pc1600 to pc2700. Does anyone know of a good motherboard reference site that would have this information?

It has the KT333 chipset which means it runs best with PC-2700. However, it will still run with PC-2100, maybe even PC-1600, but will not perform as well as with PC-2700.

When I upgrade, I'm only planning on upgrading my motherboard and my memory. I'm keeping the cpu i'm using right now. Can I run pc2700 on an athlon chip instead of an xp, or do i need pc2100 for that?

Forgot to mention that the chip i'm using now is an athlon 1.4 266fsb. Does anyone have an answer to my question or know where i can find one?

I have many more questions about the ram for this board (i want to make absolute certain that i get the right kind...). Questions such as what voltage ram it takes, what the configuration on the stick must be, can it be unbuffered or does it need to be buffered, etc, so if anyone has a link to a pdf file of the user's manual or something equivalant to that i would appreciate a link.

Let me know

kcbass -

I just set one of these up in my living room as the base for a home entertainment PC. I can't really point you to any guides specific to this particular board as it is still very new. However, feel free to ask anything you like about the board and I'll try to help you the best I can. Here's the configuration of my setup...

GA-7VXRP Rev 1.1, Latest F6E bios
AMD Athlon XP 1800+(1.53ghz) @ 1.73ghz (11.5 X 150FSB)
512mb (2 x 256mb) Crucial PC 2100 @ 150mhz
30GB 75GXP (OS Drive)
2 x 40gb 60GXP (RAID 1 Mirror) (Storage)
Radeon AIW 7500 Retail (300/400)
Hercules GTXP 6.1
52X Sony, 16X Pioneer DVD (Slot Load)
Enermax 431W PSU
Antec SX800 case
Alpha PAL8045 w/ YS Tech


I have been very impressed with this board. It overclocks nicely even with all the extra peripherals like RAID, USB 2.0, and Onboard LAN enabled and being used. The AIW cards are notorious for being sensitive to high FSB's and not o/cing too well, but this board works excellent with the Radeon. Feel free to ask away...:)

insane3d,

If you bought the board, then you should have the instruction manual. Can you look up for me what voltage and configuration of pc2700 ram the board will accept? Specifically, I'm looking for what type of 512 MB stick it will take. I think it would be 2.5 volt 64x64, but i'm not sure. I'd really appreciate it

Hey insane..... are you getting bizarre temp readings on your 7vxrp? I'm getting a steady 57/40 (cpu/MB) at full crank, and temp is 53/38 at startup. Got so many fans on it I have to anchor it to the desk. I figure the MB sensor is just plain wrong. By 20 degrees celsius or so. How about yours????

Actually, pretty much any 512mb DDR stick will work. They are all 2.5v and both double sided and single sided will work. Any of the high density memory you get in a 256mb or 512mb stick will most likely be double sided.

As far as DDR333, or PC2700 as it's more commonly known, it isn't really needed on this board. First, if you get PC2700, your FSB of your Athlon will run @ 133mhz (266DDR) and the board will run the memory at 166mhz(333DDR). This may sound great and you would think that it would be much faster than running both the FSB and memory @ 133...but it really isn't. Sure, in the benches you may see a slightly better score, but in real world use it is not even noticeable. This is mostly due to two reasons. First, the Athlon can't really use the extra bandwith of PC2700 unless it is also running a 166mhz(333mhzDDR) FSB, and to do that you would need to unlock your CPU so you could lower the multiplier and raise the FSB. Secondly, when you run your memory bus asyncronusly from the FSB, you introduce a good deal of latency. This latency offsets most of the boost from the memory running faster. Think of it this way...even if your memory is running @ 333mhz DDR, the FSB is still running @ 266mhz...so when data travels to and from the memory via the FSB, it hits a bottleneck of sorts since the two busses are not running the same speed. I hope I explained that well enough.


Anyway, my point is this. If you have the extra cash for PC2700, go for it...but it's really not needed. You won't really notice any speed difference except in a few benches, so it's up to you. However, if you plan on unlocking your CPU, go for the PC2700 and run a 166mhz FSB and 166mhz memory bus.


Also, to answer a few of your earlier questions, yes you can use your 1.4ghz 266mhz FSB Tbird just fine on the board until you get an XP. Once you get your XP, you can simply swap CPU's and you will be good to go. No need to reinstall windows or anything, a CPU swap doesn't require any changes.


Now..as far as your questions on DDR speeds.

PC1600=100mhz=1.6 GB/s bandwith
PC2100=133mhz=2.1 GB/s bandwith
PC2400=150mhz=2.4 GB/s bandwith
PC2700=166mhz=2.7 GB/s bandwith


Now, for a 1.4ghz Tbird, DDR will work fine. You want at least PC2100 since your FSB runs 133mhz. The PC1600 is for use with 100mhz (200mhzDDR) FSB athlons.

As for the type of memory you want, you want unbuffered, non registered, non-ECC DDR. Stick with some name brands like Crucial, Samsung, Kingmax, etc and you will be fine. If you have a certain module in mind, just post the link and I'll check it out for you.

That's should get you going. If you need any more help I'll keep an eye on this thread...:)

Yes, I noticed this too. The temperature readings seem a bit high. I never really pay too much heed to the mobo temps for the CPU since the in socket thermistor's are far from accurate. I don't worry a ton about the temps as long as the system is stable and can run through my torture tests. The Athlon and Athlon XP's are actually specced to run up to 95C, so even if you are running 50-60C, you are well below the high end of the threshold. I think the style of in socket thermistor on the Gigabyte tends to read a bit higher.

well, it's about time for an update to this thread, so i'll let all you guys know that i have bought my gigabyte board, and since have decided and purchased pc2700 512mb cas lat 2 (instead of 2.5), and an athlon xp 1800. can the xp's run the 266FSB on the board?

Woah...old thread back to life.

Anyway, yes kcbass, the XP CPU run a 266mhz FSB just fine. That is what they and the board are designed to run at. I'm am using an 1800+ XP on mine @ 300mhz FSB and it works like a charm. Order the XP and have a blast with your new system. :)

well, I started on my system today, and was setting the switches for the clock and ratios on the board. the instruction manual doesn't explain very much, but it's pretty straightforward. My one question is about the clock switch. There's on, which is 100 (the default) and off, which is 133. Since i'll be running pc2700 and an xp, I assume i want the off position, but i just wanted to double check

also, I just left the ratio switches set to default. I've never used them before, but i assume they have something to do with overclocking the cpu. You could probably get the info on which chip i'm using from one of the posts above, but i'll just tell you again. It's an athlon xp 1800. Should I leave the switches on auto, or should I change them to a different ratio?
