Ok here's the setup so far, I'm kinda disappointed.
8RDA+ 1.1 A1 (Vantec on NB, NB stock on SB, NO VDD Mod)
XP2100+ Tbred B JUIHB (I think, can't remember)
2x 512mb Kingston HyperX PC 3500 (In dimms 1 & 3)
Gainward ti4200 128mb
So far, the best I can do is 13*166 stable. This is 1.775 Vcore and 2.77 Vdimm.
I've taken off the FSB jumper (as suggested in some other threads).
Tried 13*180, Get to XP but errors
Tried 11.5*195, same result.
Upped Vcore to 1.825, same, BSOD's @ XP
Suggestions?
Suggest you should try to see the limit of the CPU first by keeping the FSB between 150 to 166MHZ and changing the multi.
Having found the CPU limit, try increasing the FSB but keeping the CPU MHZ constant.
You could try running memtest86 to make sure the memory is ok at each FSB increase before going into windows.
What are your temps like under load and what are your current memory settings?
My temps are fine I think, 28 idle, about 33-35 under load (SLK-800 + Smart Fan II).
Timings are 2-2-2-6.
The ram is rated for 2-3-3-7 @ 217mhz so I don't think my timings are too strict.
I have the same ram, mobo, cpu. why would taking off the fsb jumper help?Quote:

Also, you may have to give it more vcore. It seems that a lot of these guys who have 180+ fsb have 2.0V (or more). I am at 175x13 right now with 1.7vcore, but I can't see if 2.0V will get me to 190-200fsb until my sk-7 comes in.
What Vdimm are you running?Quote:

Also, there's a thread in the Epox forum at amdmb.com about removing the jumper.
have you tried taking it from a troubleshooting perspective?
Set the multiplier to something low, the memory timings to very conservative settings, and see how high of a FSB you can get and retain stability. As soon as it starts to get unstable, up the Vdimm (you shouldn't have to worry about the Vcore yet, as you should be keeping the multiplier low enough that you won't yet even be doing much, if any, overclocking above the rated speed) a hair, and test to see if it's stable.
Keep going until you find out how fast of a fsb you can pull off, then start uping the multiplier, a little at a time. :)
UPDATE: Well, I flashed the bios to the 3402 bios and now I'm stable @ 13x180, but 180 is the absolute highest FSB I can get and I'm pissed cause I have PC3500 ram which is rated to freakin' 217mhz! That just doesn't make sense to me. I dropped the multi to 8 on my proc, upped the Vcore and put the Vdimm to 2.9, relaxed timings, and I STILL could'nt get past 180. With the proc multi so low, it has to be the ram that's holding me back, but I don't understand how it can be rated to 217mhz when I can't even hit 180 with it.
Any more ideas cause I'm stumped? :confused:
Tried everything else I can think of, just can't get this ram above 180. Maybe I should RMA it. I can't understand how ram rated at 217mhz won't run above 180, regardless of timings and voltage. That just doesn't make sense to me. I'm utterly disgusted right now. :(
That is very strange in view of the fact that I can get to a 200 FSB - albeit at a mult of 8 - w/my HyperX PC3000 without having to up the Vdimm at all. Didn't try upping the mult at 200 FSB, instead I backed down to 190 FSB and was able to use a mult of 10 without upping Vdimm or Vcore. Each time I changed either the FSB or mult, I ran MemTest and Prime95 benchmark. Then I got impatient and upped my mult to 13 and it failed to POST. lol
Ridiculous :mad: :mad: :mad:Quote:

I set my multi to 8, Vcore to 1.950
I set CPU interface to Optimal
I set Vdimm to 2.77, timings 2.5-3-3-7.
Could not even get to 190 :mad:
F*cking bullsh1t.
I'm thinking now maybe I should RMA the ram. I dunno what else to do.
Well, just tried alternating sticks of ram, to see if just one was the problem. Exact same freaking results with each stick. So it's gotta be mobo or ram, but I don't think it's mobo. It's such a hassle to RMA and I don't have any other ram to try.
Well I decided to RMA the two sticks directly to Kingston. I hope the two new sticks will help, but I doubt it. Very upset about this, just can't understand how I can't get over 180mhz, not even 1 f'in mhz over.
Yeah, maybe you should RMA the RAM then. :( Am curious as to why you upped yer Vcore. Mine's at 1.63 - mult is currently at 10.5. Vdimm's at 2.62 w/FSB of 190 and timings of 6-2-2-2. CPU temp currently at 39C. Have yet to make any changes to NB cooling...Quote:

Well, I upped the Vcore just for the sake of arguement so that I knew for sure that the CPU couldn't be the cause.Quote:

Here's a recap of everything I've tried so far. So dejected about all this...
XP2100+ JUIHB
8RDA+ 1.1 A1 w/ Vantec Iceberq on NB, Stock NB HS on SB, 3402 bios
2x 512mb Kingston HyperX PC3500 (the new LL modules, came out about a month ago, 2-3-3-7 [the old PC3500 modules were 2-4-4-8])
Gainward ti4200 128mb
Antec True Blue 480watt
The situation:
No matter what the hell I do, I can't, for the life of me, get my FSB over 180mhz (and remember the ram is rated for 217mhz).
I have tried:
Any and all CPU multi's (can get up to 14 with 2.1Vcore)
Any and all CPU Vcores
Rotated the sticks in each dimm slot (both sticks together, then single, same result)
Any and all timings from 2-2-2-6 to 2-4-4-8
Cpu interface set to both Optimal and Aggressive
Any and all Vdimms
Always have FSB and Mem Frequency set to 100%
Disabled all unecessary stuff in the bios
Have all system and cpu fans on a fan bus
Tried 3305 bios (even worse, couldn't get over 166)
Everything is ROCK at 13x180. Dropping the multi to, say, 8x181 and WinXP will BSOD.
I can't even get 1 freaking mhz over 180.
I'm at the end of my rope here.
could it be your pci cards? Upping the fsb means upping the frequency to your pci cards too. Even with the pci dividers, your pci cards will still be running out of spec.
180mhz / 5 = 36mhz.
pci cards are meant to run at 33mhz.
Is there an option to make your pci divider divide by 6? That setting will bring your pci cards back into spec.
If not, then do you have any crappy pci cards installed on your system? Some cheap cards can't handle much. Remove them all and then try upping your fsb again.
FYI Patlo, the 8RDA+ locks the PCI bus at 33 and the AGP bus at 66. ;)Quote:

Guess i'm a little out of touch with oc'ing nowadays. But thanks for the info, i honestly didn't know that.Quote:

Have you been changing your settings in small or large increments? It made a big difference for me. When I made big changes I tended to lock up the system and would fail to post. When I made small changes I was able to reach any setting I tried but would reboot instead of lock up when I went too far.
How small flap, like 1mhz increases? I tried 5mhz increases, maybe I'll try just 1 mhz at a time.Quote:

I've narrowed it down to the board or ram because I can get the proc up to 14 multi.
Do you guys think the NB has anything to do with it? I put a Vantec Iceberq on there with some Artic Silver Ceramique, so I don't think that's the issue. I'll start trying the 1mhz increases.
P.S. Here's another thing I thought of, could I be supplying TOO much voltage? Would that cause instability? I always upped the Vcore and Vdimm just so I was sure that too little voltage was not the issue. Could too much voltage be causing a problem? There's heatspreaders on the ram + I have my case open so I don't think the ram is getting too hot.
Ha, you'll love this sh1t.
Tried again to go just 1mhz to 181mhz. Multi set at 13, Vcore 1.950, Vdimm at 2.77.
Windows BSOD's halfway through booting. So I reboot and do the INSERT + DEL thingy to get back into bios, and just for the sake of arguement, try again, only this time I bump the Vcore WAY up to 2.1 and Vdimm to 2.9 (max).
Reboot, XP BSOD's again. This time, the INSERT + DEL thingy won't even work to get me back into the bios. I tried just regular delete and that got me in twice, except the bios kept 'freezing' halfway through making all of my changes. Third time I got into the bios, it turned into just a blue bar and cursor across the top of the screen, INSERT + DEL still wouldn't work, so I had to power down and clear CMOS with the jumper.
This just keeps getting wierder and wierder. But now it has me wondering and maybe it isn't the ram. I've got three possibilities I believe at this point:
1. Bad batch of ram (although bothsticks of ram used one at a time produces the exact same effect so then both sticks would have to be bad)
2. Bad mobo (I'm starting to lean toward this now because it seems totally absurd to me, no matter what setting I throw at it, I can't get 1 f'in mhz more out of the bus andthe fact that even oc'ing just 1mhz seems to screw up the bios when i try to get back in and make changes)
3. Mobo/Ram incompatibility (This seems unlikely as it seems like alot of other people are having success with the HyperX. I haven't seen too many people with the LL 2x512mb PC3500 sticks though, so this still could be the case).
Sadly, the only other ram I have to try is old CL2.5 PC2100 Crucial and I know that won't go over 180mhz, so it's a mute point to even try.
I don't know. What do you guys think about the three choices above? I can't RMA the board cause I've replaced the heatsinks (obviously), so I voided my warranty. I've RMA'd the ram and Kingston is sending me two fresh sticks (same type, size) and when I get those, I'm sending this ram back to them). But if those sticks produce the same result, it still won't prove it's the board cause I don't have another board to try this ram in and I don't have different brand ram to try in this board. This is so frustrating.
What do you guys think of those three?
Actually, I don't know if anything is bad. You reached an overclocked level, perhaps not one in which you felt satisfied, but it was overclocked nonetheless. I don't believe it to be #3 since many others are using the same mobo and RAM without issues. #1 and #2 are answered by my initial statement.
I think, perhaps, that it may have been due to your trying to jump by 5 MHz increments rather than by 1. See my reply in your new thread. Also, did you check your RAM ala memtest at all prior to RMA'ing it?
Have you visited www.8rda.com? They have tips on how to reach a high FSB. Things like don't use certain PCI slots, don't hook up fans to MB headers, things like that.
Also, check to make sure your Iceberg is making full contact with the NB, mine wasn't. That's worse than stock HS.
If this is more hyperx A1 stepping combo...its incompatbility issue. However some boards will work ...as with philip and his pc 3500 are at 231 stable. It maybe a vdimm voltage issue with the new stepping maybe? ITS CERTAINLY not anything to do with cooling or anything like that. As i have the same ram in an a3 stepping epox 8rda+ and it would do 200 before and now in the A1 stepping is only capable of 180
