Buffalo 3200 cas2.5 VS Buffalo 3700 cas3?

[stompah]

I stared at newegg.com for several hours last night. During that time I read the forums a bit looking for a hint.

Buffalo 512mb 3200 cas2.5 ------ $89.50
VS.
Buffalo 521mb 3700 cas3 ------ $103

Both prices are shipped.


Should I spend the $$$ and get something better? I do not want to buy Geil or OCZ. I would like to run 400MHz at my motherboard's (8k3a+) turbo timing. I have no problem upping the voltage a few tenths to get there. Any opinions?


BTW I have been a bad senior lately. Posting dumb threads. :(

I believe that the 3200 is CH5 while the 3700 is BH5 Winbond modules.

[stompah]

I think your right. Didnt newegg used to ship 3200 BH-5 modules but now they ship CH-5?

[larva]

Yeah, I bought two of the 89.50 PC3200 modules, and they are CH5. They work fine for me, running 1:1 at 380MHz in dual channel at 2-2-2-5 with the Abit PAT-like optimization running on 2.97V. Performance is outstanding. I think they would hang in there to 400 but my cpu only has 190-193 fsb in it.

I've also used the PC3700 Buffalo. It is indeed BH5 and works well too. The pair of sticks I had did 450MHz at 2-2-2-5 with PAT like mode on the Asus P4P800 easily on 2.85V. I don't know how much more it had left in it, prob 10MHz at most.

They changed the part numbers of all the Buffalo modules at newegg for some reason. There used to be DD400-512/WC and DD466-512WB but now DD400-512 and DD466-512. I ordered my first PC3200 a week before the second, got the /WC version the first time, the non /WC model the second time. They have a different Buffalo part number on them, but the same sticker, model number (including the WC), chips, pcboard, and the spd contents are identical. They work fine together in the demanding dual channel environment. I think it's safe to say the DD466-512 they have in stock now is the same thing I used as DD466-512/WB.

*edit* sorry WB on the end there that was confusing. Yeah, I think the current DD466-512=DD466-512/WB and thus is BH5.

[GoldenTiger]

So you think it would be safe to order the non-wb Buffalo PC3700 and would I likely get the BH5 chips :)?

[Speed_Mechanic2]

No promises, but there isn't any /WC labeled PC3700 on Buffalo's website. That's a good sign, although it could just be through lack of updating. If you do go ahead and purchase it, be sure to report on your results :)

[stompah]

I PMed someone here about some second hand Geil. I dont like Geils relation with OCsystem.com but since the duty has been payed and if it works as described I should be happy.

The bigger issue here is I need a new keyboard/mouse and Newegg has a special on a Microsoft keyboard/optical mouse for $28 I could use that $28 towards my RAM purchase and stick with my ball mouse for longer... Would make life easy if I bit the bullet and bought some Corsair :D

[GoldenTiger]

I am completely stuck deciding between Corsair XMS3200C2 and Buffalo PC3700 :(.

I'm after WB PC3700 :). (BH-5) if I can get it...

[larva]

What I got as DD400-512 was identical to my DD400-512/WC stick. I believe the current DD466-512 part is identical to the DD466-512/WB and thus is BH5.

[stompah]

Problem solved ;)

Maybe now but I bought earlier when it was less than $80 and I got PC 3200 with BH-5.

Geil is awesome memory. I have DDR 500 on a retarded IS7-E (with 2.8V maximum) and it rocks 1:1 at 520 MHz at the specs 2.5-4-4-7, passing 5 hours of Prime95 (didn't try longer). That is absolutely the best I got with any memory.

[larva]

I figure that anyone who buys the PC3200 will get what they are selling now rather than what they did in the past. I've bought two sticks of it in the last two weeks and it's CH5.

[squeakygeek]

Hmm when I bought my Buffalo 3200, it had the winbond modules, and it does 230mhz. It said winbond on the newegg page when I bought it.

That is absolutely the best I got with any memory. I never said there was anything wrong with the RAM itself. I do not like buying things from a shady company or a company that has any relation to a shady company. GEIL has a relation to www.OCsystem.com OCSystem isnt a stand up company in my book and others have had major problems with them.

well i returned 2x512 buffalo pc3700 bh5 to newegg RMA so maybe youll get those hehe

[gruvin2]

grab the Buffalo PC3700 i have em running rock solid 24/7 at 400Mhz 2-2-2-5

[FattyMcNastyXK]

so which is better, to have them underclocked at tight timmings or to be at stock

[Dirty_Punk]

how can buffalo ste BH5 (PC3700) to cas3 if any bh5 i've tested can't boot at cas3!!!!! boot only at 2 or 2.5 :D :rolleyes:

Funny thing. I just got my Antec TrueControl 550 yesterday and i am SOOOOO pleased with this PSU. I am able to tweak the voltages for each rail underload to compensate for the stress, and crank up the Case fans if it needs a little extra airflow.

Ok now back to topic. I was playing with my Rig and seeing what i could get out of my Ram before My SMD grabbers arrive (last thing i need to Vdimm my MB). As i was testing i noticed that my PC will not boot with my Buffalo ram running at CAS3. How odd is that considering they are rated at CAS3. I have yet to get my Ram to 466Mhz yet with only 2.85vdimm, although as i look back i did have my timings slowest when trying for max Mhz for my ram. I havn't had much time to OC my Rig with my new PSU. My poor Antec330 started to Fold like Gumby from the OC i had going for weeks 24/7.

As far as stable OC for my setup ive had my Buffalo ram at 250fsb 5:4 2-2-2-6, 267fsb 5:4 2.5-3-3-7 (current)

[Speed_Mechanic2]

My KingMax goes up to 285 FSB 5:4 at 2.5-3-3-7 :p at 2.6V.

I ordered some a week ago, and it's BH-5.

[gruvin2]

I have mine up to 267 at 2-2-2-6 now :)

you mean 213mhz, or 267 at 5:4 ratio with 2,2,2,6 now.

btw, that's nice for cheap sticks.

[GoldenTiger]

I just got mine in, and it's BH-5 chipped. Check out my new thread for the results!

I just got two sticks of 256 a few days ago...both ch5.

[gouda96]

I was gonna get 2x256kit of khx 3200 (2-2-2-6) which has bh-5, the only chips I would consider buying...I have decided to go with 2x512mb instead, and the buffalo 3700 is just so much cheaper then everyone else when getting 2x512mb. when only buying 512mb they aren't that much cheaper, but when you get 1gb the prices are just outrageous. With the discount in price if my buffalo can't do ddr480 with 2-2-2-x with a vdim mod I can just send it back to newegg, and even if they hit me with the restocking fee it would still be cheaper then any other 2x512mb bh-5 kit.

The 865/8765 chipsets realy hate cas3, that is why it won't post cas3...lots of ram won't do cas3 for some reason with these chip sets. This stuff should be able to get to about 220fsb(ddr440) or so with 2-2-2-x and max voltage on most mobos, but with some extra voltage, like 3.2v you should be able to get very high with 2-2-2-x. I am gonna be running a 2.4c or a 2.6c at about 300fsb so the only ram I can consider is bh-5 ram.

I can't believe they stopped making this stuff...it just isn't fair.

I found a link to volt modding the IC7 http://www.xtremesystems.org/forums/showthread.php?s=&threadid=12914

[gouda96]

if you ever need any vmod go to xtreme...they will know it!

[FattyMcNastyXK]

ya but it looks very hard. One of the things that you would need to solder a wire to is not even 1/3 the size of my finger nail. Do you need a pot to control the volts? It doesn't say what you need.

[larva]

All you need to do is replace the 0 ohm surface mount resistor with 350-400 ohms. You can use a small fixed value resitor or a pot that can be set in this range. I used a 1/4 watt Radio Shack 385 ohm fixed resistor. Getting the sufface mount resistor off is the hardest part, you definitely need a fine iron of high quality and a steady hand. A little solder wick may help.

you are reffering to the is7/ic7 mod right? That is one of the reasons I am not getting an ic7...too difficult for me. I just touched a soldering iron for the first time last month. All you need for the p4p800 and p4c800 is some smd grabbers (stickied at xtreme's vmod section) and then a soldering iron. The soldering is just for the cables to the pot, and the cables to the grabber, and this can be realy messy and is very easy to do. Then you just attach the grabbers to the pins. It takes about 10 minutes to apply the mod. Then you need a mulitmeter to check the voltages...If you do a vmod make sure you have read and understand everything you can about it. If you do something wrong you will probably lose your mobo.

oh...on the p4c/p you have to mod the +3.3v line. The highest vdim you can get is whatever the 3.3v is real...lets say 3.2v then subtract .12. so if your 3.3v line was running at 3.2v the highest vdim you could get is 3.18v...this is fine for most and modding the 3.3v line is incredibly easy. In my pcp&c all i had to do was open it up and adjust the pots that were in there, and my antec tp550w was already fine...3.35 already...
