ASUS P5B-Deluxe; Problems & Fixes

I've pretty much hit the wall here. It might be Prime stable too but I haven't run it long enough to prove it.

I think it's my memory or how I have it set up and not the chipset that's holding me back here. No complaints though! :D

Last time I tried my Q6600 I wasn't very successful but I didn't push it too hard. With this new memory and a few more tricks, maybe I'll put it back in to see what it can do. The P5B works great with Dual Core CPUs. With this board I'd rather have an E8500 or E8600 (E0) than a Quad and I'd be trying for 535x8.0 for 24/7 use to get some good numbers out of the chipset and memory.

Edit: There was a little bit of extra performance still hiding in that chipset that I didn't know about, until today that is. ;)

:confused: im thinking of getting a E8500 should I ? looking to get 4.5GHz + with this mobo cuz the E8400 is like only $25 less and the E8500 and the E8600 is $80 over the E8500 and $105 on the E8400

Dom7184: The E8500 E0 seems to be the sweet spot at the moment.
After what I learned today, I can only think of two words, "Get It!" :up:

yeah now I need to make sure ill get a E0 :p:

cuz is there going to be a new line of 775 cpus i think i seen it some where :confused:

cuz if there was i think I would get a new mobo first P45 or X48 i hate how fast tech moves lol

It's end of the line for socket 775. Intel has some new CPUs coming out next month but you will need a new motherboard and some new DDR3 to run them. The way an E8500 can run on this two year old motherboard, there's no reason to even think about upgrading. Maybe Christmas 2009.

When I was playing this week I sometimes had the problem with it freezing up in the bios while making adjustments and I don't think I'm the only one that's had this problem. The bar at the top of the screen will keep going back and forth from left to right but it won't let you make any adjustments.

I'm still testing but I think bumping these two items in the bios up to 12 has got rid of that problem:
Rank Write to Read Delay
Write to Precharge Delay

It seems more compatible when using a high FSB speed. I used to have these set at 10 and 11 but now both are at 12. I'll see if I can isolate this problem further. Right now this board is running incredible for me. Very easy to set up and get decent results from.

Anyone not sure if they should stick with this board with an E8500 needs to read this thread:
http://www.xtremesystems.org/forums/...d.php?t=182051

Setting the NB to 1.65 volts is necessary for me when using P965StrapTweaker to maintain excellent memory bandwidth and stability at a FSB of 533. Highly recommended.

Edit: I thought running on the fast strap when the FSB was over 500 MHz might cause some instability but after a few hours of Prime95 blend, it looks good enough for 24/7 use.

Look for Intel sSpec Number SLB9K on the box or CPU when looking for an E8500 E0.

but there is going to be some more 775 when i7 comes out cant remember where I saw it

also my mobo fully modded just the vdroop is pencil

cuz i was looking at the ASUS P5Q Deluxe, ASUS Maximus II, ASUS P5Q Premium, ASUS RAMPAGE FORMULA, ASUS P5E Deluxe

I think the new 775 CPUs will be budget processors.

well if thats the case im going with the E8500 cuz the E8600 is to much just for the X.5

This was before they announced the i7 logo

Usually when a new line of processors is introduced, the old line is slowly phased out. There's not much point of them releasing any performance Dual cores beyond the E8600. They'd rather those users switch over to Core i7 that will have higher margins and maybe they'll be able to sell a new board or two while they're at it. I just read today that Intel has released the budget E7300 with plans for an E7400 as well.

which one ?

1. E8500 & Asus P5B Deluxe (Vdroop Pencil Mod) [Vcore, Vmch & Vdimm Hard Mod] Already Own

2. E8500 & ASUS Maximus II Formula

3. E8500 & Open Box: ASUS Maximus II Formula

4. E8500 & ASUS P5Q Premium

5. E8500 & ASUS P5Q Deluxe

6. E8500 & Open Box: ASUS P5Q Deluxe

7. E8500 & ASUS RAMPAGE FORMULA

8. E8500 & Open Box: ASUS RAMPAGE FORMULA

9. E8500 & ASUS P5E Deluxe

10. E8500 & Open Box: ASUS P5E Deluxe

11. Wait for i7 but then I would need DDR3 & Motherboard & New CPU block unless they come out with new bracket to use with my D-TEC

hello folks!

I have a question regarding this combination:

ASUS P5B Deluxe (BIOS v1236) + G.SKILL 8GB (4 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Quad Kit Desktop Memory - Retail + C2D E6600

memory specs are:

Quote:

---

Tech Spec
Capacity 8GB (4 x 2GB)
Speed DDR2 800 (PC2 6400)
Cas Latency 5
Timing 5-5-5-15
Voltage 1.8V - 1.9V
Heat Spreader Yes

---

so, how should I set CPU and memory timings? I don't plan to overclock.
Will the memory work@800MHz with this CPU? If yes...how? If someone could explain.

snoopypw: Why not get some Reapers like I'm using?

http://www.newegg.com/Product/Produc...82E16820227267

You could buy 2 sets of Reapers and with the $20 rebate you'd save some money compared to the G.Skill you're looking at.

The P5B can overclock much higher when using only 2 sticks of memory but if you don't intend to overclock then you shouldn't have a problem. There is very little difference in performance between DDR2-667 or DDR2-800 so if your memory doesn't run or isn't stable at DDR2-800 then set it to DDR2-667 in the bios.

8GB of memory is dirt cheap these days so buy them and see how it works for you. If you're not happy then dump them on EBay. The Reapers have a good reputation so you won't have a problem selling them. Hell, I'll give you $100 for 8GB of Reapers! :)

You should be able to do that, though you won't be able to OC the RAM much if G.Skill has the SPD foolishly setting tRFC to 43 like on my G.Skill DDR2-800 5-5-5-15 PQ kit.

At stock DDR2-800 it should be fine.

I think it's right place to ask this question: Does P5B-dlx have problems with new E0 stepping? I read in few places that is impossible to change Vcore on this MBO when using E0 stepping CPU.

This also relates to P5B vannila, which i own. I'm willing to buy new E0 stepping CPU, but I'm concerned about this problem. I'd like to stay with this board, i don't see reason to upgrade to P35/45.

Thanks in advance!

Yes it does have problems. I was on the latest bios & trying out my buds es e8400 & the bios was all wacky. Vcore wasnt there was one of the issues. But this was on a ES cpu, so i cant say for sure on the mainstream cpus.

Thanks for reply. We can only hope that this will change in some future bios revision.

Having no Vcore option in BIOS does limit overclock, but i've seen E8600 on P5B-Dlx at 4GHz with 1.32V, that is Vcore that MBO automaticaly sets. No bad imo, but i would rather like to find fine balance between Vcore and clock.

If I get bored of waiting, I could always buy used E8400 C0. :) I didn't see any problems with C0 stepping. Still good for 3.6GHz @1.3-1.35V.

Ya i was using my e8400 c0 & its rock stable @ 4.2 on the p5b-d. Crunches 24/7/365.

:) P965 is still great chipset.

My P5B vanilla is C2 rev. but I have crappy memory (can't go over 840MHz) so I'm limited with that. On the other hand, I'm not willing to spend too much on this build, prior to Nehalem release.

My testing seems to show that the P5B Deluxe completely ignores the tRFC setting from the SPD data within a memory stick. You can manually set it to a maximum of 42 in the bios and that's it until you get into Windows where you can adjust it higher with MemSet if you need to. If he's not overclocking then he won't have to worry about this.

With my E8400 C0 when I'd enter some crazy settings in the bios and lock it up, I found that sometimes when recovering from this and first going into the bios that all of the core voltage options would be gone. After setting most things more or less to default and doing a re-boot, the voltage core options would return to the bios. A 45nm ES processor might cause some weird issues. Pretty much every combination of parts causes some weird issue but when you work around all the bugs and get things running decently, this old board will put a big smile on your face. All those new boards are too damn easy. :)

Edit: You might want to ask this guy about his E0 on his P5B. He seems to be doing quite well.

I would not spend 250 ~ $300.00 on a 775 MB with LGA1366 around the way. I would get the CPU and keep the P965 board unless I wanted to go DDR3. I think the newer chipsets are only a refinement of old technology. With a small memory performance improvement. And, I guess PCIX 2.0.

I am going to try to hold off to next April. It will be hard, so I may not wait that long. I am hopping the i7 stuff is cheaper by then.

I want the Tri channel Bloomfield board and the cheaper Bloomfield 4 core w/ hyper-thread CPU 2.66 MHz.

After running a Quad CPU for a while, I don't think I will have anymore dual cores on my #1 PC. I have 8GBs of memory. And, I can't ever access all of it (in testing) with out the CPU maxing out (Vista 64). So, I will go with the 6GB Tri Channel.

I just think it is a bad time to spend top money on 775 technology.

Also, I would not buy any DDR3 because of the volt questions for the i7

Wow, quality DDR2 at a great price right now. I bet DDR2 will never be this cheap again.

yeah I know what you mean but if I do get the E8500 then the X3350 wont have a home :( and I plan on using one for my 61" so I dont have to burn cds :D

Hi,

I'm currently runnin' my Vintage e6700 b2@ 3.4 24/7/365 or 3.8 OC max(unstable i've tried the whole gammut except better cooling)with 2x 1go corsair xms2 pc6400 800 sticks on a 1004 Bios.

I was wondering if the 1232 and up bios' give a better Max OC or if I should upgrade to a 8500 e0 and go from there

Thanks

1236 is the latest, im going to try my E8500 E0 in my P5B before I put it in the new mobo
