mushkin mem question

[dee114]

I have a few questions about the Mushkin high perf rev 3 memory.

First, Mushkin says on it's sight that the ram will do 150mhz @ 2.2.2 out of the box. My question is will it do this witht he 5,7 setting or the 7,9 setting.

Second, if it will do 150 @ 2.2.2, then what are teh chances that it will do 160+ at any other setting, esp. 2.2.2?

Third, which do you think is better: 150:150:37 @2.2.2 or 160:160)40 at any other mem setting.

I am seriously thinking about getting some of this ram.

here's my specs.

Asus CUSL2-C 1006 bios
P3 1ghz @ 1125 150:150:37 @ 3.2.2 7,9
alpha6035 hs w/ delta 38cfm fan
256 mb(2x128) Memman mosel memory
40 gig 7200rpm Maxtor hd
sblive w/ fps2000 speakers
netgear fa3010tx nic
hayes accura v.90 modem
hp 8100i 24x4x2x cdrw

Little difference in performance between the two. You should easily get 222 at your current clock speed with the MUSHKIN Rev3. My Rev2 does 222 7 9 at 153FSB and the Sandra mem scores only get worse if I clock higher at 322 or other settings. Find the fastest FSB speed you can get at 222 and run with that.

Yes, The Rev3 can go at 150 cas 2, and it is reported to have stable at 166 cas 2. Haven't tried the rev3 before but I am sure it is better than my 256MB rev2. I am seriously thinking about getting 2 of this rev3 ram also. What I am doing now is waiting for another week or two, in the hope that Mushkin will reduce the prices, as SDRAM prices tend to drop every 2 weekends. The 256MB Rev2 is just exactly the same in everything as the Rev3. The only difference is that Mushkin take off one side of the 256MB Rev2 (It is double sides), and leaves the other side to make it only 128MB in order to make it stable & go at higher FSB. Hence, that is the birth of Rev3 (Single Side). The new Mushkin Rev.3 DIMMs, single sided, featuring eight 16M x 8 (128Mbit) Infineon chips. My 256MB Rev2 can go up to 160 at cas 222 7/9. The highest is 166 at cas 3-3-2 7/9. But between 5/7 and 7/9, the score difference is just small. What matters are the higher FSB & Cas 2

The picture of the back of Rev 3, notice there is no chip, because it is single sided


Check this out at: Modding a DIMM for performance / Mushkin Rev.3
http://www.lostcircuits.com/memory/rev3/ here are some quoted reviews:

The result of this amputation was, at first, a huge relief, the DIMM was still functional and reported the correct density of 128 MB (single sided now). The second result surpassed all expectations since the DIMM now runs flawlessly at 166 MHz and 2:2:2 settings.

Luckily, Bill Mushkin is a guy with a very fast reaction time and it took only two weeks to follow the suggestions and add the single sided 128 MB DIMM to his repertoire, now called the Rev. 3 DIMM which is now available in quantity. All Rev.3 samples tested showed the same performance as the home-made sample, that is 166 MHz at 2:2:2 without breaking a sweat.

The main advantage of using a single DIMM as opposed to two DIMMs is that the clock signal to unused DIMM slots can be shut down in the BIOS by enabling PCI/DIMM CLK autodetect . Therefore, the clock signal does not need to be diluted to the individulal DIMM slots. In case several DIMMs are being used, this advantage is partially lost, depending on the number of DIMMs and slots available. Nonetheless, adding twice the amount of load in form of capacitors that make up the memory cells , will cause a hit with regard to the highest frequency possible which is why, in general, 256 MB DIMMs are slower than 128 MB DIMMs.

3 128 MB sticks of the Rev3 at 2-2-2-5/7 and 139 Mhz.
I've confirmed that it will do 140 2-2-2-5/7, but my system is happiest and most stable with all applications at the 139 FSB.

PIII600E@834Mhz
Win2kPro service pak 2
V7700 with ASUS 11.01 based drivers
Turtle Beach Santa Cruz
A couple of Western Digital hard drives (20 UDMA 66 and 40 UDMA 100 )

For grins: Sandra score on memory 416/480. I can't complain that I'm getting an extra 243 Mhz out of my 600E with everything stable.
This system is sweet. I'll add a GeForce 3 at Christmas, which will get me through 'till Spring 2002. At that time, I'll build a P4 based system.
Add a flux capacitor and modify the matter/anti-matter mix ratio and it should max out.

Dee114, although Mushkin says on it's sight that the ram will do 150mhz @ 2.2.2 out of the box, it will depend also on your other hardware characteristics, settings & quality + other factors.

You are using PIII 1GHz PC133 right? I don't know if the 1GHz is pretty easy to be overclocked or not, but I know that the PIII 700MHz PC100 is very well known to be easier to overclock. So, your multiplier is 7.5, using fsb 150 = 1125, using fsb 160 = 1200. The Rev 3 should be fine running at fsb 150 with cas 2-2-2 on your setting. To answer your question:
1) First, Mushkin says on it's sight that the ram will do 150mhz @ 2.2.2 out of the box. My question is will it do this witht he 5,7 setting or the 7,9 setting. ANSWER: There's only small difference between 5/7 & 7/9. Try 5/7, if it can do it good, if can't boot just change to 7/9. Again, Differences are not that significant. What matters are FSB & CAS 2

2) Second, if it will do 150 @ 2.2.2, then what are teh chances that it will do 160+ at any other setting, esp. 2.2.2? ANSWER: depends on your hardware quality & characteristics. I am 100% damn sure that the Rev 3 will do 160 cas 2-2-2 on my CUSL2 with PIII 800EB (PC133). On Intel PIII 1GHz PC133, I don't know, try it. But the Rev 3 can do 160 +, now it depends on your processor capability

3) Third, which do you think is better: 150:150:37 @2.2.2 or 160:160:40 at any other mem setting. ANSWER: Offcourse, the best is 160:160:40 CAS 2-2-2 setting, cause you will have higher memory bandwith, good for playing 3D Games.
I think, your system might not get any chance to go more than fsb 160, not because of the Mushkin Rev3, but merely because of the Intel processor that will hold you back this time. Better try it, you have to increase the vcore, that's for sure.

Hi TQ, your PIII 600E has a multiplier of 6. This time the one that is holding you back from higher o'clocked is your processor. If you try fsb 150, then it might give you 150x6= 900MHz. That's an increase of 50%, which is impossible to do with air cooling. At 834MHz, that's an increase of 39%, which is very good already.

You have a decent system there. Btw, I have decided & ordered the Santa Cruz finally. It is a very good Soundcard. So you think that GeForce 3 will drop in prices this christmas?

I'd think so. Although I also think we've entered a time now when the high end consumer video cards are, from now on, going to be expensive components. After all, they are now basically processors themselves, so it stands to reason that they're just going to be expensive.
I do hope that the GF3 drops a bit. Can't see why it won't, because by that time there'll be more manufacturers with more product out there.

TQ, I am in no hurry for graphic cards, and I will take your advice to wait till Christmas for GeForce 3. Yea, I hope it will drop in price significantly.
