Twinmos PC3200 400Mhz DDR(2x512MB) Ram Review

Introduction

Again i am back with mine new review. This time i am going to review Twinmos ram. As this ram is said to be best overclocker in indian market right now. So i thought a review might help other users in purchasing ram. I got this ram around 1 month ago for 2450/- for a single stick. It comes with 3 years warranty. If u want more information about the Twinmos company please click here. This ram uses Mtec memory chips. which are good for overclocking (i mean good in value ram segment don't compare it with BHx or TCCx chips). Another value overclocker ram available in india is hynix D43 chips, but there are too many fake models of that and also it needs very relaxed timings to overclock so i think currently twinmos is the best if u want to overclock.

Packing

I got this ram in a normal plastic pack which was sealed. Opening was very simple. Also there is hologram of twinmos on the memchips to make id different from the fake ones. After opening the pack i taken out the ram chips. It is a dual side DDR.

This is the pic of the ram outside the pack. On the left side there is the twinmos hologram and on the right side there is a sticker where all the model nos and stock timings are written. if u can't read it in the pic, i am writing it down for u.

P/N: M2G9116AJAMK9F081CADT
MODEL NO: M2G9J16A-MK
SN NO:XXXXXXXXXXX
PC3200(CL 2.5 512MB DDR DIMM)

Here u can see in the first line CADT is written which means it is having Mtec power ram chips.

[break=Installation]
Installation

Installation is pretty simple. Same as all other DIMMs u have to just insert the ram into the slot. and make sure latches are locked. But in mine case it was a bit difficult. I first fitted the monster size ASUS Starice on the mobo then i tried inserting the ram i found it was fouling with the CPU cooler . First i thought i would put it in the second slot better than removing the starice and fitting it again. But after little bit or trying i manage to put it in the first slot. Then again the problem started when i got mine GTX. As, i wrote in mine GTX review. but its a ram motherboard design problem rather than ram. Here are some pics of ram installed in mine mobo.

Testing and Overclocking

Test setup

A8N SLI Premium
AMD 64 3000+
TwinMos DDR 400 2x512
Seagate 80GB HDD
Powersafe 500w
DirectX 9.0c
NVIDIA FordeWare 78.03
Windows XP Pro SP2

I have used 5 setting for testing the ram. here are the description of them. i have also added screenshots of CPUZ to better understanding of the settings.

Setting 1
This is the stock setting of the ram with 2.5-3-3-10 2T timings. Memory voltage is 2.65v.
Setting 2
In this setting i have used tight timings in the stock setting. Max i was able to reach was 2-3-3-6 1T. any tighter than this and system hangs at the bios page. Memory voltage was same here 2.65v.

Setting 3
In this setting i have used 240 FSB to test the overclocking of the ram. I made the CPU multiplier to 7.5 to keep the CPU speed stock. i don't know y but when i booted into windows in the CPUZ i seen the ram speed as 225Mhz. where FSB was the same 240. And the CPU was 240x7.5=1800Mhz. Ram voltage was 2.9v.

mem2402258kf.jpg

Setting 4
In this setting i have used 1:1 for CPU and ram. FSB was set to 240Mhz. and CPU was running 240x9=2160Mhz. Ram was running at 240Mhz with 2.5-3-3-10 2T timings. and Ram voltage was 2.9v.

Setting 5
In this setting i have also used 1:1 for CPU and mem. i made the FSB 230 and ram timings were 2.5-3-3-10 1T. CPU speed was 230x9=2070. Ram voltage was 3v. but in the 3dmarks 01 test computer restarted in the 3rd game test so i think it failed in this test. although i managed to run sandra and everest so, will post the scores.

[break=Conclusion]
Conclusion

After all testing and Overclocking i have found that this is a very nice value ram. With awesome price and performance ratio. very few value rams manage to run at CL 2 with stock voltage. The only bad thing about this ram is it doesn't like lose timings. Any lose timings than 2.5-3-3-x and mine system stops booting. So, u can't have insane clocks with lose timings.
I hope u guys wud like this review. i have given too much time to it. :)

Mods if any mistakes are there please make it right.

Cheers for TE.

good review last week only i got one for my pc costed me 2500/- for 512 mb

Edit : where to look for rep button ?:bleh:
you owe it rahul.
 
as i have written all the clocks have passed memtest for 30 mins ..... only for the last setting that is setting 5 i haven't done memtest :)
 
Test no 5. is the most crucial and revealing. Try test no.5 on 240 mhz and tell me, since i am limited only to 225 mhz @ 2.8v, beyond that it fails the test, and gives some errors.
 
test no 5 is done with 1T timings and it restarted in 3dmarks01 so no point in testing it again ..... with 1T timings it can go max of 225Mhz(even tho i haven't tested it .....) .... anyways will test it for u and tell wat is the max with 2.8v ...... i think it can easily do 230 with 2.8v and 2T timings ......
 
Saiyan's TwinMOS 512*2 CADT did 226 at 2.75v 2.5-4-4-8. But did not go beyond that at 1T timings even when more volts were pumped. Passed SP2004 - 6 Hrs and Memtest and GoldMemory for an hour.
 
^ Folks, just managed 242Mhz 1:1 on my TwinMos CADT at 1T! Timings: 2.5-4-3-8, Vdimm : 2.6v .
Got upto 227Mhz on 2.5-3-3-8, and just changing RAS to CAS delay (Trcd) to 4 yielded me NO drop in bandwidth and allowed me to go all the way upto 247Mhz. However memtest was erroring, so dropped it down to 242Mhz. Has passed a couple of runs of memtest, but havent tested thoroughly.

Surprisingly , 2T did not yield me any improvements ! Will try playing with the other settings to see if there's anymore juice I can get out of it. Both DRAM drive strength and data drive strength did not help one bit either.

Have passed on my A64 tweaker screenie to Saiyan to try out the memory settings for his Twinmos since I feel there are other timings at play. Apparently he got to 245Mhz before the system crashed out on him.

 
Great review Rahul ! It just convinced me to pick up two sticks, will post results once they arrive :)

Thread rated and repped :D

thats right eddy ..... i also get timings of 225 max with 1T timings and with 2T i can go all the way to 240Mhz with 2.5-3-3-10 ...... i am runing currently with 238Mhz with 2T timings and 2.5-3-3-10 ....... voltage is 2.75v
nice information tho thanks for sharing .....
