Yeah, staying a bit conservative is probably not a bad approach. I do want to see how this current combination runs for awhile however.

Well, after about 4 hours of running prime95 at 12 x 200 1.825 vcore, no errors so far. I'm currently dialed-in and running Mozilla and Outlook on top of Prime95 to see what that does. Current cpu temp is 38C. Nice cool room helps too.

Funny but when I started to OC, I would just try combinations that others had posted, starting with ones that seemed most conservative and working up. I had this long list on the whiteboard behind my computer. It didn't really sink in to me that a higher fsb might be interesting. At first I was simply thinking in terms of max mhz. I think I have been Intel-ed.

BTW, this is mostly a question for chizow (I think he has the same case, Lian-Li PC65plus from pcmods.com), but I'm sure others can answer as well. I have a 3.5 bay mounted temp monitor with 2 long blue wires and plastic covered sensors. How in heck do use one of those to monitor cpu temp? All I can think of is to sort of wedge/slide the sensor between the heat spreader and the cpu. But that makes me very uncomfortable. Any tips there?

And one other case related question. I have two from intake fans, one top intake fan, and a back exit fan. I put in two more fans on the side, and I currently have both running as intake fans. Should one of those be another output, or do I have that right? Regardless, I like the temps with the current configuration. Not a quiet machine though.

Sorry to have so many questions. I'm slowly starting to get this stuff (I think). A little over 3 weeks back, my only idea of a new computer was to order one from Dell. I didn't even consider anything besides Intel cpus. Building an AMD based system and then OCing was not in any of my brain cells yet. Still not sure how that all changed, other than I am cheap and started to research upgrade options which led me to...

if i were you....

this is just MHO...

air should flow from front to back or back to front... your case, front to back....

the sides sucking air is fine considering that the side fans are providing air to your HSF so that's fine...

i would however take that top fan sucking in and make it blow out as to make the flow go from side to top, if that makes sense....

i would also try to add another fan blowing out the back (you are doing a lot of sucking and not enough blowing... your fans, not you sorry...) ....

my 2 cents...

Well, Windows just locked up. Had several things running with Prime95 torture test. Booted back fine into Windows, but...

Back to 12 x 195 @ 1.725vcore for awhile.

DO NOT put the thermistor between your core and heat sink. Although it may seem relatively flat with a low-profile, it will be enough to prevent solid contact on probably 80-90% of the core. Think of it this way, slide a wedge between a cinder block and the floor. That's what you'd be doing. The way I did it is I placed used the double side sticky-tape and placed it on the OPGA packaging a off to the side of the core. I then put the thermistor on top of that tape with the tip touching the SIDE of the core. I shaved away the plastic housing from the tip so that the thermistor head was exposed and would directly touch the side of the core. I also applied some AS3 to it so that it would transfer heat a bit better.

The end results are temps that are within +/- 3C (translated from F) of what AsusProbe and MBM indicate. It also fluctuates accordingly, but polls a bit slower depending on how often you poll MBM. There is also some lag b/c the contact is not perfect, and the increased temps take longer to spread to the thermistor. I use it more of a tool to measure relative temps and compare it to my other readings to get a truer sense of temps and fluctuations under load.

Hope that helps,

Chiz

Thanks both!

BTW, in my previous message I wrongly listed my vcore as 1.725. It is actually 1.775.

for kicks and giggles..

pic

it loads up at 2400 ....

thought, HEY WHY NOT TRY 2500!!!



loads up.... but i'm at 1.9V

haven't primed it or anything... just wanted to see if this baby could do it

let's see if can go higher....

I realize that this is off topic, but it's related to Cowdog's comments on his case....the standard step for a Lian-Li with a blowhole is as an <U>exhaust</U>....are you sure it's running as an intake? As an exhaust, it works very well...

Oops, a typo. That's correct. The top blows on my Lian-Li case.

I am settling into
2340mhz, 12x195, 1.75vcore, 6-3-3-2, 2.77vdimm (don't need 1.775 - will test with 1.725 as well).

I need a stable and long-lived (~ 2 years) cpu more than I need the mhz. The TbredB voltage death stories scare me. BTW, I bought my first game (Unreal II), and I am impressed at the graphics/performance on this little system -- my "real-world" benchmark. Although this first-person shooter is entertaining, I think I need to research my next game a little more and find something with strategy for ... um ... more benchmarking.

Abit off topic but for those of you who have the 2100+ TB'b, what's the day of the stepping? I can get a hold on a 2100+ 0302 retail, how likely it is a tb'b?

i have yet to hear about a tbred A 0302... so i'm guessing your chances are going to be good.... but why get retail?

just got my retail 2100+ in Canada and it's running 12.5x190 2,2,2,4 on an epox 8rda+ w/2x2 ocz 3500el duel channel in sync. gonna let it burn in for awile by just regular gaming use , and then get my water cooler and unlease the beast. also gonna vdd mod my mobo since I can't run 200fsb now.

so is there a consensus on the best weekto try and get? i posted in the link, but didn't see too much response.

seems like 0248 may be the way to go . . . thoughts?

maybe you should change for nic to "CPU Testing Madman"!! LOL

that will be t-bred-b #5?

yup... #5

#1 1700+ JIUCB 0251 1950 @ 1.875V
#2 2100+ AIUHB 0301 2125 @ 1.775V
#3 1700+ JIUHB 0302 2170 @ 1.775V
#4 2100+ AIUHB 0302 2350 @ 1.775V

1.775V seems to be the magic number

I ordered a 2100XP+ from googlegear.com last week. Around Feb. 5th. It turned out to be an AIUHB! I ordered another Sunday and it turned out to be the same stepping code. If anyone is still interested, of course.

I almost got that chip the 03/04. tried to order the 0249 from them but it wouldn't let me check out I guess it was gone so I got the 0248 from PCnut for $110

Whoa Shim, that's a lot of cpus! I thought I was bad having 2 2100+ TbredBs (0302 and 0249).

I played with the 0302 a little at first, and didn't have much luck above about 2200mhz (forget exactly). I do think my psu had problems at that point, so I should try it with the new psu. Plus there are some other differences. I now have the nb actively cooled and the sb passively cooled. Not to mention that I am getting a better feel for the 2100+ and 8RDA+ combo. I currently have the 0249 running at 2300mhz (11.5 x 200 @ 1.775vcore). I have had it running above 2400mhz, but I have been focused the last few days on slow methodical testing of higher fsb. 11x205 ran fine as well, although I didn't test it as comprehensively (yet). I am pondering this balance between higher mhz and higher fsb. Seems like there might be a sweet spot somewhere therein.

I am going to keep both 2100+ chips and setup a 2nd system. I am currently waiting for the 8RGA mobo to hit the states (and money to magically appear in my wallet).

BTW, figuring out which stepping is better seems like a tough task. For example, later 1.1 versions of the 8RDA+ mobo have an A3 northbridge chip. Some claim that change equates to higher fsb and better OCing. Actively cooling the nb seems to help get a higher fsb as well. So in addition to better cooling, variability in each cpu, and other obvious factors, it seems to me that there are some subtle factors influencing how well these 2100+ TbredBs are OCing as well.
