Another Gigabyte GA-8IPE1000-G "problem"

post #1 of 9
Thread Starter 
Hi all....obviously my first post in this forum...

I've recently "upgraded" my mobo, got one from the title...BUT, since then, all I've got were PROBLEMS! Put aside all of them, I've somehow mannaged to solve majority of them, but there's still one:It seems I can't set it to "work" at 133MHz CPU host (533MHz FSB) and 266MHz memory frequency! I have 512MB DDR266 and Intel Pentium4 Northwood (s478; 18x100) and when I "leave" this "setting", it's all ok: in BIOS i can see CPU host @ 100MHz and wheather I choose "Memory Frequency For" 2.66 or "auto", I get "memory frequency clock" 266MHz! My memory, altho not from the "quality" series, can somehow mannage to work at this clock. Problem starts when I set CPU host freq. @ 133MHz (at which freq. my P4 operated "all its life" on my old ASUS mobo, with the mem. clock set to 200MHz...just to mention that...). According to mobo manual, I am supposed to get NEW "memory freq. for" options for 133MHz, which would be: 2.0 (at this one my memory would be "operateable" = 266MHz), 2.5, and auto, WHICH I DON'T! I still get those 2.66 and auto, and of course, using that, memory clock goes to 354 MHz and my DDR can't work at that clock - after "save and exit" I can't even POST...I have to clear CMOS, it would give me "default" value for CPU - 100MHz, and I am at the beginning again!

Questions: Is there something I'm missing?! Why can't I get those "memory freq. for" values from the manual?! Does any of you guys have any idea, advice, anything....except "go for DDR400"?! I will appreciate anything... By the way, my bios ver. is F5, and as I understand it's the latest one!
Thanks to all of you....

well the 8IPE is designed for ddr400. so thats why your kinda running a forced divider cause of your ram.

Thx for your reply... If I understood you correctly, if I buy DDR400, when I set CPU to 133MHz I would get those "2.0, 2.5, auto" values, but because I have this DDR266 I am not able to get them.....or did I misunderstand you...?!

Welcome to the forums.

What you're running into is called a CPU:RAM divider. Basically, the CPU and RAM both run off of the systems external clock. To get FSB, the clock is multiplied by 4 for P4s, and the DDR speed is twice the clock speed. The stock speeds for your CPU and RAM are 100 MHz and 133 MHz, respectively. Running at those speeds, you have a 3:4 divider in place, which is very common with that generation of components.

If I'm reading your problem correctly, your BIOS give you the option of multiplying the external clock by some number to get the DDR speed. The 2.66x factor when your CPU is at the stock 100 MHz gives you the 266 MHz stock speed for your RAM, and when you up the clock to 133 MHz, a 2x is not available. Please correct me if I'm wrong on any of those points. I haven't used a Gigabyte board before, but it sounds like you are looking in the right place but not getting the options you're hoping for. Have you tried using the auto option with the clock set at 133 MHz or even at 100 MHz? I'm wondering if auto doesn't match the RAM speed to the CPU speed, giving you a 1:1 divider, which would give you DDR266 speeds at 133 MHz external clock.

Even if you can't get anything other than 2.66x at 133 MHz, your RAM may still be workable. Check around the BIOS menus for RAM timings and RAM voltage (vdimm). An extra notch or two of vdimm can help a lot. Also, loosening the RAM timings (increasing the numbers) also helps with overclocking. Using those setting together may well work to get your RAM stable.

Hopefully the auto setting will solve your problems, but if not, try tweaking the RAM settings to squeeze more out of your existing components.

@Taeric> One GREAT "THANK YOU" for your reply and trying to help me solve my problem....I really REALLY appreciate that!

Now...back to the topic:

You are right about all of that...that's exactly what is "happening"!

YES, I've tried to use "auto" option for both 100MHz and 133MHz freq's, and I still get THE SAME THING: "memory freq. - 266MHz" and "memory freq. - 354MHz" respectively! Like, I used "2.66" divider, multiplier, whatever it's called... By the way, "memory frequency xxxMHz" is greyed, and I can't manualy change it, which I could do with my old ASUS mobo! Accually the most of my attempts to "make it work" were made with this set to "auto", 'cause I was hoping for the same thing as you mentioned! I even tried changing CPU to 133MHz and "save and exit", hoping that in the next bios entering "2.0, 2.5, auto" options would appear! BUT, in that case I can't even POST, not to mention entering bios again! And again - WHATEVER I do (I've also tried some other CPU freq's - 105, 110, 120...), I always get those same "options" - 2.66 and "auto"...and whichever I choose, I get memory freq. (which is, again, GREYED) CPU freq. x 2.66 !

Vdimm....oooooooooh....another bios "issue", or another my misunderstanding...I've tried that also, and with Gigabyte you cant put "absolute" values (like for example "2.7V"), but you can increase Vdimm (and every other voltage) for like +0.1V and +0.2V (those are the options which I have on my mobo...)...but it doesnt metter - I've tried raising voltage for +0.1V and the default was read as 2.61V....when I "saved and exited", returned to bios, voltage was STILL 2.61V (btw, setting for Vdimm was "+0.1V")....I set it to "+0.2V", restarted, and Vdimm WAS STILL 2.61V! JESUS! Like my mobo is "locked" for some setting changes (of course, it isnt, but that's the feeling I get...)! RAM timings...well they "work" - I tried "tightening" them (2-2-2-5) just to experiment a bit, and my system became unstable @266MHz....I loosened it to "default" 2.5-3-3-6 and it was back to "stable"...but still @266MHz! I dunno....I might try experimenting with voltage and timings again, but I can't imagine that my RAM will work stable @354MHz which is "the only option" I get when CPU is set to 133! It really isn't very "good" and expensive DDR....it even made a bit of trouble at nominated 266MHz with my old mobo...thats why I kept it @200MHz back then...

Thank you guys, again...Taeric, special thanks to you...I guess it's just time to go for DDR400...but even then, I guess I wont calm down untill I understand why it wont let me choose freq's the way manual says it would!

I just read through the appropriate sections of your mobo manual, and I still have no clue. Your mobo is supposed to be fully compatible with DDR266 RAM, so that shouldn't be the issue. I see where you were talking about getting additional RAM options now that you have the clock speed set to 133 MHz. I have no clue why it isn't working as it should. You may want to try rolling back the BIOS to an earlier version if you really want to get to the bottom of things. You may get the best results out of upgrading to DDR400, but then you'll never get to the bottom of your current problem.

I read your posts and I own GA-8IPE1000 which has a 2,4GHz/512/533 SL6SH cpu with Corsair's Twinx1024-3200XLPro (2x512) dual channel. The system runs very smoothly although I don't know if it can run 1:1 at 200MHz. Now it runs 4:5 at 168,3MHz of 200MHz 2.0-2-2-5 (readings from CPU-z). So, can it go any faster than this ? Full Throttle and the BIOS is a little bit tricky....Thanks in advance

I have the same problem. The system keeps setting the CPU clock to default. Turns out its the CPU (Celeron D) thats not supported. This mb supports all the S478 P4s, but none of the Celeron Ds

Went to gigabyte.com and downloaded bios "F5" this has the latest processor support.

I will try to flash my bios now, I will post rely if sucessfull Wish me luck!

:swearing: It still don't work! This board just dont support Celerons!

I was going to change my 3ghz Celeron, next month, to a 3ghz P4 and see what diffence I get. Looks like that will have to be this month now, as I hate having a mb that I cant use.

Flashing the bios on this gigabyte board was very easy. I used the onboard software with no problems. However, you do need a 3.5" floppy disc - has anybody seen one of those recently, I had to buy a box of them
