The ESR of 18mOhms is too high. The stock Nichicon HM or Rubycon MBZ 6.3V 3300uF caps got about 10-13mOhms of ESR.

Unfortunately only Panasonic is available here, what is the worst outcome if I recap with Panasonic FR?

You can use Panasonic FR without any issue, nothing will happen, I've used them to recap 50+ boards.
On the CPU VRM there are multiple caps in parallel anyway, so effective ESR will be much lower. As long as the caps don't heat up excessively (which they surely won't) and you won't notice any instability, you are good.

Thanks, guys.

Back from vacation, more to come soonish.. So long:

Didn't boot unfortunately..

I order my capacitors most at Mouser. Its not cheap though.

The board says, you have clocked too far. ^^ I guess you managed to start somewhere at >250-260MHz FSB, right?

Seeing the postscreen, I see my typo. D42 --> B42
At least it is the bug fixed version. I just saw, the non deluxe 2.0 BIOS version still has a (tiny) bug in the code. I need to fix that someday.

Alright a little update. Installed my very first water cooling setup using a WB2 (WB3 is going to be used in a proper build with the Zalman Reserator). I think I need to get some 90 degree connectors and adjust the tubing. No leaks! (yet). Still getting the bubbles out. CPU temps are MUCH lower. Idle used to be 46c @ 2.0v and now it's 30c @ 2.0v. Holding a little POT to adjust the ram voltage.

Cool, I like older Zalman blue color. They made some pretty good things back in time.

Yep I love it. I’ll show my blue build soon.

Are these sticks any good or they just rubbish? (I have a matching pair for both models). Unfortunately they are 512MB but maybe they’ll let me go a bit higher than 235 FSB?

I guess you already know about these lists:

Corsair XMS-PC3500C2 Rev1.1 (2-3-3-7-1T) = Winbond BH-5
Corsair XMS-PC3200LL Rev1.1/2.1 (2-2-2-6-1T) = Winbond BH-5
Corsair XMS-PC3200LL Rev1.2/2.2 (2-3-2-6-1T) = Winbond CH-5

@all: What do you think about the Gigabyte GA-7NNXP? Very little info on the web about the board except the price was enormous for that period ($200), and it's not a great overclocker. 🙁

As far as they go I couldn't squeeze more than 235 out of mine either.

3500C2 should be the best Corsair Winbond BH5 bin. However, dual ranked sticks may work mediocre on NF2 boards. Single sided modules work a lot better.

3200LL 1.2 are CH-5 sticks. I would guess something like :
220MHz / 2-3-2-6 / 2,85V
240Mhz / 2-2-2-5 / 3,2V

I also own that board. I need to recap and test it someday. It does look nice. A good CPU VRM in my eyes.

Imagine you do a modded BIOS for that board after the recap. 😀
That board definitely looks like it could handle some heavy load.

I will do it. I need to finish some sidequests first. Recaping a A7N8X, finish my Infineon AT-6 chip binning...
Thinking of the Gigabyte 7NNXP, I will have to check the needed capacitors. I hope, I have all needed caps here.

Thanks for those links. I didn’t have 2 of them.

Thanks for the info. I didn’t have much luck with the 3200LL. 3500C2 is arriving in a few days.

Guys, what about Infineon HYB25D256800BT-7/BT-6? 256MB, 0320 & 0340

I finally made a pair of 256MB BH-5 sticks, installed them in my water cooled NF7-S 2.0 (vcore at 2.0v) running vram at 3.2v via a POT. To my horror, I still cannot go past 235 FSB, no matter what multiplier I run. Windows fails to load. Could I just have bad luck with the chipset on this board? Could it be the Kyocera capacitors I’m using (installed them because that’s what I had on hand). Could it be the memory controller in the CPU? Not sure what path to investigate next. Any advice would be greatly appreciated.

VDD is 1.7V? Did you try 240+, like 245, just for the test?
20+ years ago my Abit boards were all retarded in that way, like no boot at 225, but 240 booted.

Yep 1.7v. Tried 240, 245 and 250.

I guess you tried to play with her around 235 or 236? Loosen timings on RAM?
